Who knows about reprograming computers.
1997
Stock LS1
156K miles
What can i expect to gain out of a computer reprograming?
Basically i wanto to get all i can out of this stock engine as is. meaning im not ready to swap cams heads or do a rebuild just yet.
Will a reprogram gain me any noticable performance results?
And can a reprogram be used to select different shift points. Its an automatic obviously. Really want a 6speed but oh well.
Id like for her to shift down a little quicker while im cruising. As of right now i damn near have to be at 3/4 throttle before she decides to wake up and get with it.
My trans am was this way also. But it had a button located in the center column labeled transmission performance. Basically you turn it on and it fed the tranny a new shift pattern making the car seem more nimble due to earlier shift points and holding gears longer. GM stopped putting this button on the trans am after 94 but the wireing still exists on later models if any one has one and wants to check it out. Coolest factory option ive ever seen on a TA. Not sure why they didnt put it on camaros or why they stopped putting it on TAs for that matter.
Anyways thanks for any info. Also im located in indianapolis indiana. Who knows a person in my are that can squeeze the most out of my stock set up with just some tuning and computer work?

Yes it will make a difference and yes it will be noticeable.
I'd recommend at least an air intake of some sort and exhaust system to get a little more out of it and make sure you do the mods before the tune obviously.
Chuck @ COW is who I and many others have used on the forum. He definitely modifies the trans shift points, pressures, torque management and all that.
The other thing that is really cool about Chuck and I speak from personal experience is he will talk with you on the phone and re-adjust as necessary if you're not happy with your tune in any way. He's in Westchester NY I believe but look him up on here, you won't be disappointed.

There are some superb tuners thru out the United States. Unfortunately some are not as good with recalibrating the C5/C6 automatic.
Rely heavily on the Forum People who reside in your geographic area to point you to a local Tuner who can provide you what you are looking for and will work with you if your not happy with the tranny calibrations that you desire. they need to be C5/C6 Corvette knowledgeable.
There are people who tune using a dyno only. Thats great for making the most power but, you need someone who will also give you a really good street tune. That is accomplished by installing a professional tune in the PCM and then by driving the car on the street while data logging on the street. The data logged info is used to fine tune PCM calibrations that control LONG TERM FUEL TRIMS during cruise and AIR FUEL RATIO during Wide Open Throttle. Timing is also adjusted to eliminate any Knock Retard under heavy load conditions. The MAF is also re-calibrated. After data logging several times (up-dating the PCM each time) any errors are corrected and your LTFTs will be perfect.
Finding that person can be tough. Anyone with tuning software can tune. Hell,,, I own my own EFI Live V2 tuning software and dabble but, I will not attempt to tune your engine let alone an automatic trans.
Fortunately for the people in the Northeast we have Corvettes Of Westchester. Chuck Mosello! The man is a tuning ARTIEST! He's one of the best tuners that Ive ever met. He does phenomenal automatic trans re-calibrations.
As for what you will personally get out of a professional tune, its difficult to say. It all depends on how your car is currently OEM Tuned. If it really rich from the factory, tuning will clean that up and the engine will respond really well. You will notice increased throttle response and best of all, an increase in fuel economy. As much a 2-3 MPG better. Call and ask the tuner that you choose what he thinks you will gain. You will gain some HP & Tq but the real benefit is the efficiency, better throttle response and your new tranny calibration will shine. It will be a different car!
I easily gained 3 MPG over stock MPG and a lot more power after Chuck COW tuned our 06 MN6 Coupe. I installed headers, ported TB and a VARARAM. My C6 was pig rich after the mods and I dropped down to 22-23 MPG highway. After Chuck tuned it, it runs fantastic and on long trips, I see 28-29 MPG.

What can i expect to gain out of a computer reprograming?
Basically i wanto to get all i can out of this stock engine as is. meaning im not ready to swap cams heads or do a rebuild just yet.
Will a reprogram gain me any noticable performance results?
And can a reprogram be used to select different shift points. Its an automatic obviously. Really want a 6speed but oh well.
Id like for her to shift down a little quicker while im cruising. As of right now i damn near have to be at 3/4 throttle before she decides to wake up and get with it.
My trans am was this way also. But it had a button located in the center column labeled transmission performance. Basically you turn it on and it fed the tranny a new shift pattern making the car seem more nimble due to earlier shift points and holding gears longer. GM stopped putting this button on the trans am after 94 but the wireing still exists on later models if any one has one and wants to check it out. Coolest factory option ive ever seen on a TA. Not sure why they didnt put it on camaros or why they stopped putting it on TAs for that matter.
Anyways thanks for any info. Also im located in indianapolis indiana. Who knows a person in my are that can squeeze the most out of my stock set up with just some tuning and computer work?

The way I see it, I worry less about how much power you're making and more about how much you already have that you're not taking best advantage of.
A properly tuned automatic trans can be tons of fun and the "feel" of the car (which is your only real gauge of how much fun it is to drive) goes a very long way....
Call me any time if you want to talk about it more.

It will absolutely make a difference. How much depends on the tuner and your mods. I too am a EFI Live user. I've tuned my car as well as one other. I plan on doing more and more as I learn the ropes. Its a long learning curve for sure!
Here's a few suggestions:
Find a Good Tuner Find someone who specializes in Tuning and LSx Motors. A good tuner will do both street and dyno tuning. A dyno tune in OK for power gains, but a street tune will make for a complete tune. After all shouldn't the car be dialed in for real world driving?
Supporting Mods Power comes from cylinder pressure. Increased cylinder pressure comes from more air, more spark, more fuel. Get an air intake, get some exhaust, and do some cooling mods so you can run a bit more spark and keep knock away.
Engine and Trans. Tune Definitely tune both engine and transmission. Whats the point in squeezing all the power you can out of your engine, when your transmission takes it away. Fine tune those shift points on the dyno and get as much of the power to the ground as you can. There is no reason for these cars to shift after 6,000rpms.
Mail Order Tune Mail order tunes are a waste IMO. You are not correcting LTFT's and MAF transfer function. With an increase in air efficiency, you need to adjust your main VE table for the car to run smoothly and efficient. Invest in at least a dyno tune and you'll get the most out of your money. For a car with bolt-ons I would expect to pay $300-500.
If there is not a shop in your area you may want to sign up on the HP Tuners or EFI Lives forum. Ask around and you may find someone local that can tune it and show you everything.
Good Luck!

THANK YOU THANK YOU THANK YOU.
Thats for all the replies.
I much more interested in a street tune than a dyno tune just o make power. But i can see where the combination of both would be the total package.
Im getting about 19miles per gal average now? This is under 70% average dialy driving and about 30% petal to the metal driving. Sound rich to you guys?
Im located in Indianapolis Indiana. Home of the indy 500 obviously,..surel there is a well known tuner in my are that specializes in vettes,...i could drive her up to lingonfelter..im sure i spelled that wrong,...but im not sure i want or need to go that route.
Like i said i just want to get the most ouf of this engine and tranny that i can for now. When she blows or when the tranny fails thats when i will start thinking real performance.
She is a daily driver i just want to be as quick as possible with what ive got. Would love to tune it myself, but i know its beyond my experience.
Thanks again.

You have a bone stock '97. Anyone who has looked at one of those tunes knows it already has a very aggressive spark map. You're already at 28* advance at WOT & that's one of the things we adjust on the newer cars into that range. There is a bit to be gained on your car by taking it down from 1.25 EQ ratio in PE mode to something like 1.13 EQ.
You want to do something that'll affect your car's performance, put a free flowing air filter in it, get a can of MAF cleaner & clean the MAF, get a can of carb cleaner & clean the throttle body. Check the torque on your intake bolts and look over all of the vacuum lines. You want a tune? You have a couple of guys right on your doorstep in the INDY area who have done probably thousands of LSx tunes, know what they're doing, and won't charge you $500 for a $150 job.
