newbie here so if this is in a wrong thread don't poke me too hard. I have a 2006 GMC Sierra crew cab SLT and added: throttle body spacer AFE cold air intake kit flow master Jet EZ programmer Question is... with the Jet programmer. It has either a jet pre-programming choice...which I've been using... or I can go through everything from gears to fuel type to shifting RPMs, which I haven't tried in fear of jacking up my tranny. Is there a better setting for programming besides the 1 jet EZ preprogram? The shifting seems hard and always at 5500-5900 rpm, damn near redlining all gears. any input is appreciated!
