Cm2250 Ecm help

[Stantheman]

2013 cm2250 was de mandated for off road use. Straight pipes. Truck ran good for 4 months or so. All of sudden it started over boosting like high 40’s no power no smoke. Mechanic cleared codes ran fine until it started idling like it has some hot rod cam in it. Like it was loping and turbo was boosting 1-2 pounds. Once in a pull it would over boast. All sensors have been replaced turbo swapped out fuel pump rebuilt engine rebuilt same time of de mandate. I finally have my mechanic in agreement that it’s a bad tune. So if someone would please reach out and let me email my tune to them and fix it I will compensate the work. I’ve dumped over 10k in this thing and wish I would have just replaced the scr can. Thanks in advance
