I just had my 05 gt dynoed for the first time today. I thought my numbers would be better. It was on a dynojet and the temp was 80.2 with 21% humidity.
max horsepower-267.09
max torque-272.65
I have a jlt cai, sct tune by brenspeed with 92 octane, 4:10 gears and slp lm's. Is my tune weak? Any suggestions? My a/f is 13.0

Did the shop that you took it to do a before the mods dyno pull?

also, is your car an automatic? i could kind of see those numbers if it is an auto trans.

My 05 was 265 stock and then 307 after my mods that are listed below.

As one stated before, weather could also cause not a so hot hp increase.
