I feel like a broken record on this forum. I realized I wasnt going to get my tune figured out as quickly as I wanted so paid a somewhat local guy to send me a tune. I had already bought a mpvi3, credits and licensed my pcm so he adjusted my tune remotely. I waited a couple days for the tune, then he sent it this morning. Its not much better than what I already had. Im getting a lot of stumbling at low/mid acceleration & small backfires/pops at about every other take off. VCM scanner shows Im running lean I believe, I'm not sure im even reading the graphs right at this point. I contacted the tuner but have yet to hear back from him. I couldnt find anyone local to set my tune which is why I bought the mpvi3 in the 1st place. But I'd like to drive my truck without stumbling & backfiring.
1) Does anyone notice anything off with my tune and/or log?
2) I have tried MAF & VE tuning before I bought a tune but apparently I was doing something wrong because I couldnt get it to work for me. If I bought a wideband, would this make the process easier?
