Can someone help me understand these tunes?
I have a 2018 3500 l5p on 37’s tuned and deleted with a ccv reroute and banks big air. Nothing else done to the turbo or the engine. Bought the truck tuned through VSE and hit them up to fix my speedometer as it was about 7 mph behind the actual speed. They sent over some files. I flashed them as instructed. Didn’t fix the speedo and felt like my truck was lagging, had some deadpedal and shifting felt softer with less power. Hit them up again and they just sent me all these files as the fix. I have no fucking idea what im doing when it comes to reading these tunes. I understand the hiss and rumble, but just curious as to which files to flash the truck to give it its most capable stock power. Vse will not answer any questions or phone calls in the last week so I’m reaching out to you dudes to see if anyone could help out. Thank you in advance
