Any luck? Can you be more specific? Performance wise maybe 2 tenths of a second. This is on a bone stock car. If you are in an area where they only sell RFG gasoline. I would not even bother with the Hypertech. You might even lose performance

Absolutely. You can change shift points for each gear, change shift firmness, change the cooling fans turn-on/turn-off points, change the rev limiter setting, etc. You can usually pick them up very reasonably in the parts for sale section. Two things to watch out for is they are car and model year specific, and, make sure whoever you buy it from returned their C5 to stock with it before selling it to you. If they didn't, it won't work on any other car. Another advantage is that once you no longer need it, either because you're selling the car or increasing your mods, you can resell it, after returning your car to stock tuning with it. Well worth it on a stock or lightly modded car, IMHO. Cheap, easy to use and effective at what it does.

My 02 was hitting the rev limiter on the 1-2 shift, and the HIII fixed that. I also noticed the change in shift firmness which was positive. Buying a used one was good value for me.

You didn't mention your original ratio, btu if it was the 3.15... then you have a 1 in 1000 chance you may... might escape the problems encountered with the Hypertech.
But if you're going from the 2.73... it's just a matter of time before you'll be forced to get a valid reprog.

13.2@107 if you know how to launch ,(experienced at the track) assuming you have 3.15 gears. Add on another 3 tenths of a second for the stock gears. 13.5@105 with stock gears. Another factor to consider is that all LS-1 motors were NOT created equal. I have seen anywhere from 280-310 rwhp on bone stock motors. This can make a big difference in your times too..

I called Hypertech this morning to discuss why they advertise on their Website as well as in the instruction manual that you can change Gear Ratio to non stock gears and they state on the web page it is correctable all the up to a 4.10. It seems alot of Forum members have had the same problem....Do we have enough for a Law suit or Class Action....I mean this is False Advertising....Any members who are attorneys, feel free to chime in....Thanks John
