    5.3 engine swap won’t rev past 1500 RPM

    So just had a buddy check it, limp mode is off. Working on figuring it out now. Just stumped.

    5.3 engine swap won’t rev past 1500 RPM

    It only has a MAP code, and the signal on the MAP is within spec. What is the limp mode? how would I know it’s in it? thanks
