I've got an 02 Z28 with an A4, headers, exhaust, K&N FIPK, 3800 stall TC, AIR delete, and just go a tune done at RPM. I only dynoed 311hp/333tq.



It gets bumpy at the end. Can anyone help me understand why it would dyno so low? It runs and accelerates fine. I only had a 1/4 tank of gas when I dynoed, also I stalls out occassionally when the tank get that low now. There are no codes showing. Please help!


Oh! We did have some problems with the dynobrake not disengaging. My last few pulls were done with one of them manually enaging and disengaging the brake.
