Newbie tuner here, but tuning a 5.3L with a Elgin stage 2 sloppy cam for my father. Motor is completely fresh but basically all stock other than the cam and springs. Have made some progress with the tuning but I seem to take 2 steps forward, then 1 back each time.
I can actually drive the truck now but seems to have no power when you step into it. The bigger issue I have is that when it begins to warm in temp and try to start it back up, it wont. Now if I remove the mass airflow sensor from the cold air intake, it fires right up and almost seems to run better. This is a manual 5 speed trans as well, all trans info has been deleted.
Really trying to understand why and if its even possibly to delete the MAF? Attached is the tune file that is currently flashed. Really hoping to maybe chat with someone who is more of a expert in tuning! It seems lean and the next step would be to dial in the timing.
Thanks for all the help!
