For a moderate street program, what should the degree of timing be on my chip? Also, what should the A/F ratio be? My truck is my everyday vehicle and I will put about 15k miles on it a year. My only mods will be chip, 4# pulley, tr6's, fast air kit, and traction bars. Should I need anything else? Thanks for the help.

yeah im interested in this also, Johnny Lightning programed my chip when i bought the pulley, and i've been getting detination. i'm curious to see where its set now and what is a safe program for me to run on an every day driver. thanks, shane

 

You're probably experiencing added timing from the ECU as it senses cooler outside air. If your fuel is questionable(MTBE added?), this would just add to the problem.

Can't help on the "programs, etc."

Yeah, i am in Illinois and i think I know what your saying about cooler weather. Is it throughing off the computer are you saying? I always thought during cooler weather my truck would run better. But in my case i have to much timing does that sound right? my question is if i reduce the timing now for the cooler weather... will i be able or need to up it in the spring? i dont wanna keep doing that. all im looking for is a safe program for me to run year round with the 4# pulley...

 

Well for a "mild-street-daily-driver-tune" I would say you should not be over 16* advance and an A/F over 11.

My street side is 16* and A/F is 10.0 (read>>rich as Bill Gates). I have never had detonation even in 20* air.

whats the abu# of the chip im running a Abu 12 and never had and det and its getting about 30 degrees here

 

That is 30* total timing not 30* advance.
