Hey guys since i had no luck in my last thread i will try one in here. I have a 07 LMM Duramax and its currently having fits iam thinking its the turbo positioning sensor as it will build to 20lbs boost then it sounds like its got a waste gate and its set wrong because it after hitting 20 it instantly drops to 13ish and hisses very loudly. SO basically what iam saying is i would like an upgrade to get away from the variable vane turbo but that is far as i have come with my decision, iam not sure which way to turn in getting a fixed turbo. Iam wanting atleast factory spool characteristics but would prefer faster and more boost. I like the looks of the Garrett line of ball bearing turbos but iam unsure of which size is the one i need. Iam open to any suggestions.:st:
