ok so i finally got my truck logging with my predator all dialed in after playing with it for a while. i finished it about 2 weeks ago or so and what a difference it has made. ever since i owned the truck and if you would floor it it made a detonating sound.....not good lol. and my mpg was about between 13-14 virtually all city driving and now after i adjusted the ltft's and the pe the detonation is gone and mpg's are averaging over 16 now.....im utterly impressed

Great to hear!
I get that same detonation issue at higher RPM, couldnt hear it till i got my aftermarket exhaust. I just assumed it was the torque mgt retarding the spark a bit. One more reason to get a diablosport product i guess.

I actually have had a hypertech programmer for a while now, but i always hear that pinging detonation sound around higher rpms like when i floor it on the highway, I have never done anything about it but since you say yours is gone now, should i be worried about that myself or is it even a big deal?

A little detonation, like for 1-2 seconds is considered normal by GM when first hitting WOT. I'm sorry,but I don't agree with that.

i dont agree with that either any detonation is not good.... that is not a normal engine sound well i guess for our trucks it might be but to me its an abnormal sound a motor should not make. i would fix it. plus when i run wide open it runs and pulls better and i dont worry about hearing a big bang from hearing abnormal sounds (i.e detonation)

did your detonation go away after your exhaust or did you just hide it from the noise of your exhaust....i didnt do my tuning till after i put my exhaust on (just a cat back dynomax ultra flo ss) but even after i put it on my detonation was still there
