First tuning, hopefully someone has already made a file

I talked to Jessie's performance, they seem like they know what they're doing but I'm poor so spending that kind of money is hard to do when my grocery bill goes up $50 every month. I'm in honey grove Texas, not far from Dallas. Very small town of 1600 people so finding work here is tough. Usually my customers are coming from the bigger cities, the last truck I built was from an hour and a half away. I will try that file in a bit, replying from my phone making dinner ��

Thank you for working on it, I really appreciate it.

I have tuned dozens of 6.0Ls myself. Stock engine should not require a ton of dyno time to get it right. Match the file for DBC or DBW. Swap the injector data. Put the MAF data in that matches the engine size and MAF. Vans have small MAFs with an entirely different MAF curve. Are you using the Van MAF or Truck MAF? Part number would be helpful.

I haven't been back in a while, between work and preparing for my family to stay in my house for a week I'v been busy. I'v driven the car a couple times, but my alternator died and I parked the car because I'm pretty pissed off at her right now So far it seems to run better, and shifts ok. I need to put some miles on it so it learns a bit more. After next week, and spending who knows what on a new alternator. I appreciate everyone's input, and I will let you know how it goes when I can afford an alternator

Iv been busy working on other projects, but finally found time to work on my junk. Is there anything in the tune that would turn off the alternator? Sounds stupid I know, but I can't seem to find anything else. All my wiring is 2 years old, and everything is working as it should. I have multiple ground wires that are all new and everything has been checked. The original alternator makes 6.6 volts, the new alternator makes 6.8 volts, the 3 other alternators I tried all are in that range. All the fuses have been pulled and checked for continuity, battery sits at 12.5 volts. Iv at a complete loss, this makes no sense at all. The only other thing I can think of is a bad resistor in the wiring harness, but it's a BP automotive $800 harness that's 2 years old.

What am I missing? I feel like an idiot, charging should be super easy.
