What is wrong?? Ok I have a 99' ss that I just got done installing this list
Fast 90/90
42# injectors
underdrive crank pulley
pacesetters and true duals
peformabuilt level 2 and 3500 stall
MS4 and prc dual springs
Tuned by RPM in lewisville
and all I made was 380 hp at the wheels? Dynojet dyno, 80 degree weather
It made 309 STOCK with an air lid only??? All that for 71 hp??? I had harland sharp rockers on it from texas speed and 1 broke within the first 20 miles of driving?? I had to put the stockers back on to make it run right?? any one else have this experience with them??i am pretty dissapointed!

Ya if they had the converter unlocked that will definitely cause the low numbers..
But i wouldn't worry soo much over Dyno numbers, take it to a track and see what it does.. Hell it may help you win some money one day

Definately seems like that cam and 90 fast with the headers should have gotten you to the 400 rwhp level. Is the tune super safe ?? Can you tweak it a bit ?? How much timing are you running, what kind of fuel ?? Keep us updated, I'd like to know why you aren't making 400 rwhp as well.

I am pretty sure the converter was unlocked, 93 octane, and yes I can tweak I have Hptuners! I can't wait to get it on a track, all I want is to run about a 7.5 or a bit faster in the 8th. I have juice too but it isn't tuned for it yet!
