I had just got my 2003 GT Dyne and it was quite upsetting to say the least. My Moods are as followed

-BBK under drive pulleys
-BBK Cold Air
-Acura 75MM TB
-Acura plenum
-Typhoon Intake
-BBK Short Headers
-X-pipe
-Pipes Violator Series Exhaust
-Diablo Tune

WHY AM I AT 229HP??????? and 266 TQ. I know that HP isn't everything, but I think a stock dyne is 240. What did I do wrong? I was going too got with some comp cams and forged internals, but I'm just so disappointed at my results.The Dynosaid that I was running to lean at about 2500-3000 RPM but level off after that.

 

Is it a high octane tune? R U sure the dyno itself was calibrated correctly?

 

perhaps you need better injectors/fuel pump. you should be somewhere around 250rwhp with a good tune. closer to 260 if you had longtubes. try putting your PI manifold back on, typhoon has been proven to lose HP in that RPM range actually and until you get into a blower or a turbo you really dont need to upgrade it.

2v's unfortunately dont respond very well to bolt ons, but your results are what a stock car should be dyno-ing. stock you get around 225-230rwhp i believe.
