ok here's the short version:
94 k2500
355 vortec flat top pistons
gm performance cam
bbc tbi red top injectors/ 97 vortec fuel pump
I am running $OD and have the wideband wired up
Now when I start it up cold it runs super lean. But when it warms up it tends to get pretty close to normal. I'm attaching 2 datalog files one is a cold start the other is operating temp idle. I've been reading a ton but I cannot seem to get it richened up. I want to drive it to datalog but I don't want to burn a fresh motor up. Also if I give it gas it has a lean pop or backfire. Any help would be awesome
Thanks
