I installed the predator tune in my truck, and was running it really great for about 2-3 minutes with no knock retard showing up, then out of nowhere it started pulling me down 8-10* of timing (between 90% and WOT). Im wondering if this is a heat issue (causing detonation), or something to do with the computer not liking the new timing. The temp gauge shows nothing over 200, but im thinking this is inaccurate because the predator gives me 210 when the truck isnt even running... I just replaced the knock sensors (apparently for no reason), and the computer is still throwing a low ks voltage warning for both sensors after it starts retarding.

Any and all thoughts you have on this issue would be greatly appreciated.

 

you will have to go in and retard your timing at wot with it. if that doesnt help you will have to contact johan at runningwiththedevil.com and ask him. i got rid of my predator. he can send you a tune also.

 

If your truck is a 99 you will have to send Johan your stock factory file and let him make some changes to it. I've done several that had the same symtoms.
