Hey all, had a few questions. My 08 Envoy 5.3 had an afm lifter lock up, so I installed an LSXceleration kit with a 212/218 stage 2 cam, non afm valley cover, new lifters, 3 bolt cam gear, and a K&N filter. It starts and runs nice, but it doesn’t want to go when you step on the gas. Replaced the pedal sensor and throttle position sensor, no change. If I get it up to speed it goes, but I can get it stuck on the slightest incline, put the pedal to the floor and it just won’t go. Now I haven’t had it reprogrammed since putting the kit in, and I tried disconnecting the brake booster sensor, no change. Am I having a problem simply because it hasn’t been reprogrammed yet?
