Finally got an Uprev tune done on my 2008 Base model with Stillen Gen 3 intakes, Berk test pipes and Invidia Gemini dual exhaust. The gains were impressive and it drives like a whole new car. Special thanks to Tim at Xact dyno.

 

I think I read a few articles saying Dynapacks read higher than most dynos but I suppose a tuner can make any dyno reader higher. Most important thing is that your happy and your Z is tuned. I'm looking forward to get my Z tuned with Uprev soon. My lady friend's dad is a big GM tuner (a celeb on Ls1 tech forums lol) and I'm trying to convince him into start tuning Z's and G's using Osiris Uprev.

 

Yeah I believe they read a little higher than others, However they are much more accurate at measuring the gains making them a little better for tuning. The Osiris tuning is a great piece of software.

 

+1 on the higher reading dyno. Either that or control X! lol Nice results either way OP.

 

Nice gains.. surprised your ecu didn't adapt to the mods a little more... figured baseline would have been a lot higher

 

Did he dyno it in different gears?

 

Huge gains, looks like it screams above 5000. A agree with those dynos reading high, but who cares? Numbers mean nothing, your torque curve is fat in the low end and power comes on strong as torque starts to fall off. Congrats man, looks sweet.

 

i have an 08HR and when i tuned i was 246 torque and 276 hp after the tune on a mustang dyno which are known for being low.... so he is prob pretty close to true, maybe a little skewed. from what the guy that did mine (steve kahn) he said the hr's dont respond to tunes as well as the de because they were built pretty dang good to begin with.
