HPP3 help. Will using the HPP3 "engine tuning" hurt power once LT's are installed and EGR/AIR are deleted? I'm pinging at 5k+ now and wondered if this had anything to do with it? TIA.

Re: HPP3 help. yes, if you're pinging right now, do not use their tuning...
It increases timing, smoothes out the timing curve (stock near peark torque timing is reduced to prevent detonation), and leans the car out...
As soon as I got LS1 Edit, i copied their tuning... not very impressed...
