Anyways i followed it to the best of my ability as i have never used this software before although i have tuned pickup trucks with hp tuners so im not completely unexperienced just unexperienced with cummins. So after i got to the end of the @m*m^2 guide i decided to load the tune on the truck and it did not go well. The truck starts fine but as soon as it starts it lopes extremely hard. The best way i can describe it is turning the key off and turning it back on over and over. Zero throttle response. Luckily i loaded the stock tune back on and it is back to normal. So has anyone had this happen before? To me it almost seems like there was a problem loading the tune on the truck but i didnt want to try again. Also if anyone would be willing to review my file and tell me how bad i messed up that would be greatly appreciated. I was going to have someone tune it for me but after reading about all the bad tunes on here I didnt know where to go that wouldnt butcher the tune. Thanks

would recommend getting on mumble, and talking to the man himself about reviewing your work, or any other options he might have...
