L33/LS1intake/LT/SS2 tuning help
Hey folks, long time reader first time poster. Anyway I've got a 84 Grand Prix that I swapped a while back with a ls1/4l dropout from a fireturd. LS1 eventually ate a lifter and i decided to toss my sloppy stage 2 cam and pac springs in my l33 i had sitting vs even bothering with the ls1 immediately. It will run start lope and even somewhat drive but seems to be running absolutely pig rich. smoke from the exhaust and i wreak of gas fumes. Im attaching the tune i have on it currently and a log file. I would really appreciate help getting this sorted and learning to tune better.
EDIT i had a broken injector wire i didn't see that screwed the last log up. fixed and drove the car huge difference. attached a clean log(updated original link)
