I have a 2004 GTO 5.7 M6 car with mods and a Jesse tune.

I was looking at numbers on the OBDII scan and added the Transmission Torque PID.
I pulled her in 1st gear and found out that if I spin I loose Trans Torque really fast but if I come out the hole easy and hit it if it holds it will do good after about 6 times the best was 378 ftlb but I'm still having trouble hooking up.

OK now for the question.

How far off is that number to actual FTLB of Engine Torque?

I was thinking my engine was way stronger.

Thanks in advance
