I Need Help!!!!!!

[SpeedyBolt]

Guy's I am at aloss and need help! I just installed a 4# pulley and a "custom" programmed DiabloSport chip. I am getting just a little detonation at 3/4 throttle and beyond. I called the peolple who programmed the chip and they said I needed to go with colder plugs. I guess my question is what kind of plugs do most of y'all use and what heat range would be good for my application.Any help would be greatly appreciated!!!!!!!!!!!!! :beer:

I use Denso IT22's with my 4lber.

PLEASE DONT change your plugs to fix detonation...

Have someone use a scan tool to figure out how much timing you are running

You DONT want to damage your engine

Does anybody know someone who has one of those scan tool that would be nice enough to tell me if timing is my problem. I installed the chip on Saturday and noticed the problem and put a bottle of octane booster, Rampage Brand, and went to a local track and I didn't have any detonation. Does this sound like timing???

[Silver_2000]

Yes it sounds like too much timing

Where is Whitney ?

Plus he can actually help by selling you a chip that isnt goingto blow up your motor

Is there a number that I can get in touch with this guy? My chip came with a paper that said "we tune for power and any detonation shold and will be corrected." I guess its under warranty per say, maybe I can get them to de-tune the chip a little?

If I found somebody with a scan tool, what would be the corrcet or too much timing??? :confused:

[Silver_2000]

Depends on the gear and the throttle position

Terry can give you better pointers

Diablo chips are FAMOUS for too much timing
