Thread: TURBO 5.7 possible TUNE issue.

    First add fueling until you achieve ~11.2 AFR in boost across all rpms

    Then:
    Raise engine rpm limits cutoff drive limiter table all to 6400
    TCM rpm limit is way too high for a stock cam - change this to 6000 MAX

    thanks for your reply bro i appreciate it! I have another issue. When i let off the gas sometimes, it will continue to speed up for another second or two. it happened in my most recent test drive and it is a common issue that ive heard of but havent found a solution. have you seen this before? Thanks!
