    I have never looked at a 4.3 tune. The 5.0 and 5.7s like about 3 degrees more timing. PE delay is too long, I like it at zero. PE is also too rich, typically around 10.5 to 1. If Normally asperated I set it to 12.8 to 1.
    I set RPM Bypass to 400. Torque management settings are usually a matter of preference.

    Default Update?

    What were the final results on this 4.3?
    I may try one also.
    Thanks
