I have done a lot of searching and reading before posting. It seems all situations are different obviously. Did the 411 swap on my 383, so now my truck has the brains of a 02 Chevy Express Van. VATS disabled, some minor things already flashed when I got it. EGR turned off, bank 1 sensor 2 and 3 turned off, alt codes turned off. I corrected the cyl volume to 0.78451. EGR is still on the engine for now, pink wire on the connector is ran to the 411 as per Lextech spread sheet. Truck runs and drives excellent. Way smoother than the old black box. No misfires. Only issue is when you start it. It fires right up, then starts to stumble for a few seconds. Sometimes shutting off and having to re start. If I give it some throttle and let it run for about 8 seconds at 1000 rpm, then let off it will idle all day around 600. I did raise the idle on the tune to that from 550. Trans seems to shift fairly early. 1-2 will shift very soon, and the 2-3 shift is kind of soft, not firm like it used to be. So with all that being said, where do I start? I am reading and trying to understand the tuning lingo. Just clueless on where to start. Any help is greatly appreciated. Vehicle specs are in my sig. Thanks all!
