Quick/easy/cheap horse power?

Tune it, is it something that can be changed back, or is it an another 3-400 dollar charge? I've seen diablo sport, bulldog, hypertext programmers, as well as some other branded chips, are they at all recommended?

The Best of Corvette for Corvette Enthusiasts





A BETTER plan would be add ALL the bolt on mods that you want to enhance power/TQ and then do a tune.
Here are the EASY things that flat WORK with proven gains:
VARARAM. Best cold air intake PERIOD! (MHO)
HEADERS Easy 30HP
TUNE "AFTER" all the MODS
NOTE! CAT BACK EXHAUST adds a small amount of HP approx 10-12 on a good day. Purchase mufflers for the sound quality that pleases your taste/ears and doesn’t drone more than for the additional power.
Remember; EASY FAST CHEAP or FAST RELIABLE CHEAP! Pick two cause you will NEVER have all three!!
Dyno tunes are fine for bragging rights but,, you also need to tune the car on the road for the best dynamic tune. Unless the tuner spends a lot of dyno time adjusting the VE Tables and MAF tables, your fuel efficiency will never be optimized! Those can easily be adjusted and optimized on the road by doing an AUTO VE and MAF table adjustment.

- Dyno/Street Tune (This should come at the end of your modding unless you're looking to learn how to do it yourself and are willing to invest the $1,500 or so in an HP Tuners setup. Otherwise, you're looking at a few hundred bucks to have it re-done periodically.)
- Electronic Exhaust Cut-outs (Pretty cheap and you get a bit of power - and a lot of noise - on demand at the push of a button, I'm not sure how much power these are really good for and how noticeable that power is)
- Cold Air Intake (forum consensus seems to favor the vararam, others exist and you can pay more or less than the vararam)
- Headers (only worth the cost/hassle if they're long-tube (~30 hp) - short tubes won't give you more than 5-10hp, consider your local smog requirements, here in CA long-tube headers will not pass the visual smog inspection)
- Cat Back Exhaust & X-Pipe (only do this if you want a more aggressive exhaust note, the power gains are small at 5-15hp and you're not likely to notice it)
- Cam (again, this can give you some decent power, but here in CA you'll have a hard time passing smog on a cam that will give you any kind of real power)
- Heads (you can make some decent power with a well done head package but you're going to pay big bucks if you don't know how to do this yourself and it's best to do in concert with a new cam)
- Supercharger (biggest bang-for-the buck, many kits are CARB certified so you aren't likely to have smog concerns, many cars running 500rwhp with conservative tunes and not a lot of boost, plan on about $6,700 for install and tune)
There are tons of other parts you can buy and bolt on to your car that will gain you very little if any power despite how they're advertised.
Another big thing to be aware of is that as you add power (depending on how much), you push some of the components of the driveline to the limit of what they were engineered for. The LS1 bottom end isn't all that strong because it's aluminum rather than iron and the internals aren't forged. The A4 transmission is known to start giving problems after a while with added power (think heads/cam and/or supercharger).
Good luck!
You didn't day if your car is an auto or 6 speed----If you have an automatic--the best mod you can do is a stall converter---It will make your car 3-5 tenths quicker in the 1/4 mile without touching a single part of your engine !!!--It will make it launch like a beast with stockish HP--
With still retaining all the driveability of the car--smog legal--warranty unaffected--I wouldn't go too wild with the stall speed--but something in the 2500-3000 range is very friendly-
Mileage not affected much at all
Other than that a cold air intake of some sort ( must be CARB legal in calif)
Some sort of cat-back exhaust---
Next on the list I'd go with maybe some shorty headers ( good for around 10-12 RWHP ) and CARB legal
Finally I like changing the rockers to a 1.8 ratio on a stock cam--They can gain about 15-20 RWHP and it's not a hard install--( you'll have to get better valve springs--some Z06 take-off are cheap and work very well) OR if your car has 243 heads already you won't even need new springs
I wouldn't go the NOS route--Its just a pain in the but worrying anbout a motor lean down and failure- Filling the bottle all the time--Pain !!-If its just a daily driver i'd skip it--
Of course a street driven tune of some sort or even a mail order tune would absolutely help performance ,shifting on a A4--I would NOT waste my time on any handheld tuner --Only exception would be a Diablo which address more table that reuire ajusting with some mods---
