Hey guys Im kinda new to the tuning game and I've been having some issues I cant seem to work out. First off Im trying to figure out the ideal AFRs for my engine. Its a 2006 lq4/4L80 swapped into a 74 chevy stepside with shorty headers, dual exhaust with h pipe and fake flow masters, ebay intake, and a BTR stage 3 truck cam 218/224,.552/.552 113lsa. I've downloaded all the tutorials and they seem to recommend starting rich, leaning around peak torque, then rich again through redline. I tryed this method first and dialed in afrs with my wideband but was having some KR isssues and I noticed that just about every "professional" tune Ive downloaded to compare seems to have a flat afr, usually around 12.2 so now Im going that route and in the prrocess of retuning afrs. Is this the best way to go about a street tune? just a flatlined afr all the way across the board?
My other issue is shift points. I started with my shiftpoints set at 6000 but it really didnt feel like it was pulling up there so I lowered them to 5800. Now if I make say 4 wot passes, it may shift at 5700 once or twice but is usually shifting around 5400-5600rpm. Why is it not shifting where its programmed? Any help would be greatly appreciated.
Thank You,
Robert
