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.

I hope that you are right about the tune. Personally I was more impressed with the outcome from the car we tested in December with no intakes and no tune. A number of factors could be why the tune did nothing. After it was all said and done we added 100 octane race fuel in and tried to bump the timing. The ECU still kicked it back and did an override.

I have no doubt the headers work and you will all love them! I want to get a litlle more in depth in the tune next time because I feel like there is room for improvement. I can tell you this though, I am throughly convinced that the aftermarket long tube CAI's hurt the torque and power throughout the entire curve. Regardless of what anyones says. At this point I have dynoed enough different 370's with the same outcome.

Thanks, Tony
