I'd put money on the MAF being your problem.

My 03 tahoe with whipple pings like crazy when I lightly throttle up in overdrive about 1800 rpms. I've reduced timing and messed with a few other options, but that doesn't help much. I think the added heat the blower is adding to the air temps are really hurnign it, even with the bypass setup. I'm going to relocate my IAT sensor after the blower so the PCM will see real charge temps. I think I can then tune around the issue some. I may mess with that this weekend.

I got Allen Nelson sending me another tune with lower timing. I also ordered HPTuners so I can log and send that to Allen then get revised tunes by email. Got my wideband in and it shows near perfect A/F ratio. I need to change my IAT sensor too.....it's on my list of things to do...
