installed heads and cam lost torque
I have a 99 a4 with 2800 stall 3:42 gears hooker shorties xpipe with corsa exhaust programing by ed wright. when I dynoed my car when I had the stock heads and cam my numbers where 322 hp and 334 torque. since I installed my heads and cam my car made 360 hp and 322 torque at 7000 rpm I purchased this comb from the horsepower store my cam specs are 222/226 duration 566/569 lift 114 lsa. my heads are stage 2 with stock compresion they flow 290 cfm . intake is z06 with bbk throttle body
DOES ANY KNOW WHAT HAPPEND TO MY TORQUE? COULD THE CAM BE IN WRONG?
I CANT EVEN PULL A HOLE SHOT FROM A STOP ONLY IF I BREAK REV IT . BEFORE I ONLY HAD TO PUNCH IT.

Definatly a problem somewhere. If you arnt sure, I would have a professional look at it. It may cost you a little extra but it will likely be worth it in the end to make it right.
At least I would pull the trouble codes from the computer to start off.

Something does not seem right. I have a similar setup type car and had similar (little lower) numbers before I had a camshaft put into it.
If you had the work done, I have them go over it again and yes sound like the need to retune is a possibility.
