born before the computer age, 2012 Colorado 5.3 with a 1900 supercharger, it has the tune supplied by the manufacturer, VCM scanner shows PE about 1,200 rpm to 2,600rpm then gone, running 14.68, 1 bar MAP, I'm towing a travel trailer, also my throttle position sensor reads 83.9% at full throttle, pedal signal says 100%, and I know TPS should read 88% at full throttle, Is this a dumb question??? i'm lost, just bought a wide band, won't be here for 10 days, need help, UPDATE--- have hp's scanner on 2 computers, the 1 im tuning with was outdated, so i updated it, got my wide band in and guess what--- wide band says I have PE, the scanner says I have PE now, and other stuff works in the scanner works now, woopi, even the tps reads 99.6, could my scanner have been corrupted some how ?????
