Hey guys, new to posting on threads so forgive me if this in in the wrong area. Supper long post but trying to include all info
Im having some trouble getting my 2010 Jeep JK Ls swap to run right. It's a Gen 4 5.3 LC9. I know I have to get it tuned and have an appointment with the dyno in a few weeks. I purchased a mail order tune with the hopes it would get me running good enough to drive it to the tuner an hour away, but it runs worse with the mail order tune than the stock tune been trying to get ahold of the guy but seems like he's dogging my calls. I did rebuild the engine and changed a few things, I deleted the AFM/DOD and changed out the VVT cam for a stage two Texas speed cam. I won't include the full parts list for my engine rebuild as most of the parts are just gaskets, seal, and hardware. But to mechanically delete the AFM/DOD and VVT I used these specific parts. Besides these parts the engine is stock.

Onto the next step I messed around with the tune a little and got it to run and idle decent. I disabled all the DTC's for the VVT and AFM/DOD as well as Disable both those functions in the tune. The issue now is, when I start it up it revs high then coughs or stutters quick then catches itself and stays running. This is all with the MAF unplugged. When the MAF is plugged in, it starts and stalls right away.( The MAF I'm using is from a Camaro because that's how the wire harnesses is set up. It's a diff sensor than the stock truck MAF.) I'll attach the tune file I'm using, if anyone might be able to help and or has some suggestions that would be awesome. I can't drive it rn to take any logs because I'm re-gearing the diff's I started the re-gear but stilll waiting on the rest of the parts to come in the mail. Also I have a 4" cold air intake that I fabbed up.
And its throwing these DTC
P0010 Permanent (which is one of the DTCs I changed to No error reporting and unchecked the SES light)
P0102 ( I think because I unplugged the MAF)
P057C permanent
