    We need to know what vehicle you're working with. Post your stock or current tune for help.

    I live several hours away from the nearest tuner. I would not have spent $750 on a MPVI3 and 8 credits if I could get it tuned by someone. But thanks for pointing out the obvious!

    Thanks for posting. I'm interested to see what you worked out vs. what I've got. I'm in the same boat, project got put on hold so I haven't had much time to mess with it.

    Oh I get it. Have you tried to start tuning it yourself? Post up a log or explain what part are you having questions about? Also what is the engine mods? Just the cam and valvesprings i take it?

    There should be a few good writeups for idle. I think Rinkrat? Log a few more PIDs like knock, injPW, and a few others. Do you have a wideband? What all is done to the engine? It shows it was a 5.3 originally, now a 5.7?Have you changed injectors or checked fuel pressure? Some guys disable dynamic airflow and tune the maf first, other guys fail the maf and tune the VE first. Its up to you. Being its an ASA, I would do the VE first. You might want to disable DFCO, EGR, and any other tests that will skew your trims. It looks trims were adding 50 percent fuel. So thats pretty far off lol. Set the MAF fail to 0hz, make sure the 3 maf DTC's are report on first error. Setup up a histogram/chart that plots STFTs over a VE table, copy and paste by half, well do full for the first couple corrections.
