Fast Intentions exhaust and header comparison. Before and after UPRev tune (Dyno)

chuckd05

Yes of coarse I am looking at the whole graph. Wwhat I am saying is on that dyno sheet Tony says the tune picked up no gains... only cleaned up a/f

I find that extremely hard to believe as I have seen with my own eyes 5-6 dyno sheets after an uprev tune where there was power made through out the entire RPM band on a car that came in with full bolt ons and some just TP/Intake ... No, not as much as posted here, but in some circumstances 15hp was gained around the same RPM as this dyno with just a tune on a car with injen cai, berk tp, greddy exhaust...

It seems as if he is saying the tune gave ZERO hp and ZERO tq and I find that very hard to believe.

This is a thread about a COBB tune, which in essense is the same thing as uprev as it just allows you to tweak the a/f and timing.. the gains are really good, and yes I know others have seen no gains from tunes, Im just posting this as a reference, take it for what ever its worth to you..

Cobb Tuned @ Altered Atmosphere – Awesome Gains!
