STOCK COMPUTER&HPP3 I HAVE '02 GMC W/5.3 AND A 4L60E.MY MODS ARE AIRMAX INTAKE,POWERAID TB SPACER,180 POWERSTAT,AND GIBSON SUPERTRUCK CATBACK.MY QUESTION IS SINCE HPP3 IS FOR STOCK VEHICLES AND WITH THESE MODS MAKE IT LEAN,WOULD RESETTIN THE COMPUTER WIPE OUT THE HPP3 OR WOULD THE COMPUTER RELEARN THE SETTINGS MAKING THE MODS I HAVE WORK BETTER.I KNOW HYPERTECH LEANS OUT THE A/F BY 1.2 POINTS.IF YOU HAVE A STOCK VEHICLE AND INSALL THE 93 PERFORMANCE TUNE AND THEN INSTALL THESE MODS IT'S ALREADY LEANED OUT ,SO THIS WOLULD MAKE IT WORSE? WOULD THE COMPUTER RESET THE A/F TO THESE MODS OR WOULD IT WIPE OUT THE HPP3 ALL TOGETHER IF YOU DID THE RESET MOD??

Re: STOCK COMPUTER&HPP3 HPP3 power tuning has always caused 3-4 degrees of KR. I think the tuning may be useful to folks with bone stock vehicles(+160 thermo) running on 93 octane.
