Got predator today..HELP!!!!!!!

[99RedSVT]

Ok i got the predator today and installed there performance pulley tune.Jumped in the truck and started to take her for a test drive when i heard my baby pinging like crazy so i pulled over and used the pulley/performance 90mm tune it says its for 99-00 lightning's only.Well i thought a 99 had the 80MM MAF. Well i drove home and this tune isnt making the truck ping.I also went and mnodified the tuen as well by adjusting the timing a hair advance and also riched it up alittle bit. Oh and also firmed up the 1st to 2nd shift alittle. What have u exsperienced predator guys found out works the best. Check out my mods and tell me what tunes or modified paramaters i should use.THanks guys

You had better talk to your tuner, detonation is BAD :nono:
See what your tuner says, but get that thing on a dyno, dont just trust your ears, it can be lean and not ping, I melted 4 denso's on the dyno with a 15:1 A/F and the truck did NOT ping. Be carefull, engines are expensive, and every truck is a little different.
