does anybody have any idea how to prevent this w/o having to put everything back to stock?

 

doubtful the system is adaptive to high temps

 

Contact GIAC or your tunerabout it. www.giacusa.com and see what they have to say. You could get a mbc and turn the boost down a little, but that may cause other issues if your actual boost is much lower than requested by the ecu.
The hotter the intake temps are, the more likely detonation will occur if your ecu cant compensate with enough timing/fuel.

 

Sounds good guys, I think i will try to get a hold of GIAC. you guys are awsome when i need help. ttyl

 

You could try using a heat range cooler spark plug also. If youre not already using them, put in some NGK BKR7E gapped to .028. You should be using those anyways if youre boosting anywhere near 20 psi.

 

I do need to put new plugs in. i will do that this weekend and let you know how it goes.
