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 [>:]

Seems way to low, especially the torque for a tune and cold air. Ive seen stock 5 spd cars dyno almost 280/290.

They seem pretty low, especially considering it was on a Dynojet.

I've no clue how many miles you've got on your GT but could it be something simple like a clogged fuel filter, fouled plugs...? My car lost power on the dyno when the tuner tried advancing the timing. For some reason my car just wouldn't take it. Is there a possibility the a/f ratio reading of 13 was incorrect? If you're tuning to a a/f ratio that is false either due to improper calibration or faulty sensor that could screw everything up. I really am grasping at straws here. I hope you find out what's up.

What gear did they conduct the pulls in? Is yours auto or manual?

^^^exactly what I was going to ask^^^

Sounds like the auto tranny 3rd gear dyno run syndrome

brad25

3rd gear, I have a manual with about 14,000 miles

Go smack your tuner and tell him to do the run in the correct gear. It should be done in 4th.

Are you serious, the place I went to fidn't do my tune, that was brenspeed. I did my dyno runs at torque freaks areputable place supposably.
