I've tried all three of these & here's how they compare, No dyno results or real facts, but SOTP comparison is obvious & does not need Dyno results !!!

First of all... Superchips & Hypertech did NOT properly correct a 3.42 axle change...

Powerloader... first impressions... By far the best & worth the wait (5+ weeks w/ overnight shipping), especially if you need the axle change correction. Noticeable, obvious, low end pulling power, quick A4 downshifts, very firm shifts (easy tire chirp into 2nd).... WOT performance is also excellent although not as obvious & noticeable as low end & shifting.

Hypertech... Nice choice of user options. Did not properly correct 3.42 axle change. Minimal performance gains, not really noticeable. Firmed up shifts to a nice compromise, but not as firm & fast as Powerloader. Great for fan temps & medium improvements in shift firmness & shift points. Changed options several times & went back to stock without problems.

Superchips... Did not properly correct 3.42 axle change. Little or no noticeable difference in shift firmness. Questionable changes in shift points (hit the rev limiter a few times but could be the 3.42 problem). Slight performance gains, but not as noticable & obvious as Powerloader. Gas mileage dropped about 3+ MPG. Returned unit twice for re-programming of 3.42 & shifts... both "uninstalls" crashed the PCM requiring it to be re-flashed (twice). Many people seem to like the Superchips & have no problems, but this is my experience.

I came to the same conclusions as you EXCEPT I did not notice any improvement with the Superchips. The Superchips also crashed during uninstall requiring the PCM to be reflashed.

 

Everyone on here seems to like the Powerloader best. My concern is future mods. As I understand it, you send in your current configuration and the people at TTS fix a custom program that you load.
What happens if you continue to change things? Frequently??
Should you wait until you think you're finished?
What about a stock version? Is this ever a good first mod?

Lots of questions I know, but I am an admitted neophyte. :confused:

I am new to C5s. Can you give me a website link for powerloader?

 

http://ttspowersystems.com/
Their website gives very little info, you'd learn more doing some searched here on the forum for "Powerloader" topics.

Or check the forum "Mall" for vendors... some of them have some info.

Trust Me Danny, you dont want to powerload your ZO6!!

vetterdstr :cheers:

 

Why? I need some way to modify the temps the fan operate.

 

Yep...the Powerloader is the best, IMHO...check my sig...not bad numbers for a 4-cat A4, eh?

Cheers,

Steve

 

Just a question, but how did you know that it did not accurately correct for the 3.42's?

 

The DIC shows error codes, indicating the problem(s)...
NONE with Powerloader!!!

 

Ahhh...ok then. Thanks. I'm still new to the Vette stuff. They're pretty different then those FBody thangs. ;)

 

A more accurate measure than SOTP is 1/4 mile runs at a track.

Hypertech installed at the the track after many runs netted me a ~.15 reduction in ET.

Mods
A4, 3.15 gears, Vortex, Corsa Indy, 160 stat, TB bypass and BFG DR
s is what was on the car when I put in Hypertech.

Definitely worth the $200 I paid slightly used from a forum member.

The SOTP is so obvious (after trying both/all programers) that track runs aren't necessary!!! I will have g-tech times soon, but... the Hypertech wasn't an option for me since it didn't correct my 3.42 axle change...

I tried Hypertech (first) & if it had corrected the axle change, I probably would have been happy with it & kept it.... but since it didn't I had to try others & found the Powerloader to be far better in all other aspects also.

If a hypertech knocked .15 off your times, I'd bet that P/L would lower them .3 or more. It's really a noticealble, obvious SOTP improvment over Hyper, and no comparison in the A4 shifts!!! Only drawback to P/L is not being able to go back to stock, although I don't know why anyone would want to.

My Hypertech (for 1998) is for sale for $200 in the "C5 parts for sale" forum.

I see that the gears would be a problem. Maybe in the future I would go power loader. But each mod you make requires more money for reprogramming and I don't want to go crazy, YET

Good luck with the GTECH

 

I got a call from Craig from www.superchips.comyesterday in regards to my order...a Microtuner for my 2001.
They have had a delay with the production, but he assures me that I will be in good shape in a week or so. They have re calibrated the Microtuner for the 2001 C5. They are making it more aggressive then ever before and they just want it perfect before they ship.

I will say this for Superchips. They do correspond and relate to the customer. Unlike some vendors who ignore their customers inquiries.
I waited 3 months for a Powerloader with absolutely NO information. Not even a I'm sorry we are so backed up.Please be patient......NOTHING. :mad

That's not the way to deal with customers. I don't care if your selling gold at half price.
The customer comes first and a simple acknowledgment is all that is asked for.:D

 

The only mods that really "REQUIRE" reprograming are major ones, like axle changes, heads, cam, etc. These mods most always require (custom) programing... Standard "bolt-on" mods like adding an exhaust later or adding an intake (as I did later) do not require reprograming... Even the "stock" programing is optimized (somewhat, in GM opinioin) for the parts/ mods that are on the car when "stock".. Re-programming also only cost $75.
If you have an A4, the shift changes alone are worth the price of the P/L... it's like a new/better tranmission!!!


Many people are happy with Hypertech and/or Superchips, unfortunatly they just didn't work for me.

 

Goldman, the only reason for putting the stock programming back in the computer is so if Chevrolet re-flashes the PCM, it doesn't screw up your programmer. I always put mine back to stock before I take the car in for service. Then any updates the dealer downloads to my PCM are saved in the HPP III whe I re-program it.

Vetterdstr. Why not. Can you provide more info? :seeya

 

I'm also interested in either a Powerloader or Hypertech. I know that you can take the hypertech off when you need to take your car to GM for service. What about the powerloader? If they flash your PCM will you lose your program? And which one is better for a 6 speed? :seeya

 

BTW, I also have a HPP for sale for a 2000. It's new, never been used. Email me if interested. BTW, no problems with it, but my wife got it for me for my B-day, not realizing it doesn't do as much on a 6-spd. I had one on my SS and loved it. :cheers:
