finally have my 03 duramax ready for tuning, have a 4 inch straight through exhaust, K&N intake, and EGT guage, 167kms on the truck, looking for the max that the stock allison will handle, I dont tow and dont use the truck alot.
I am very familliar with gas tuning but diesel is fairly new to me, ive read up and have done some minor tuning with good results, looking for recomendations for a 100-120hp tune,
at this power level is it a good idea to get a boost fooler so I can go above the hardcoded boost?
