    02-05 trailblazer/envoy axis change

    02-05 trailblazer i6 (p10 iirc)

    Axis change (switch ve tables to map instead of tps)

    A certain "other" company has it I won't name any names (slow serial interface)

    I haven't tried it yet but it seems like if it works it could mean a way easier way to deal with forced induction on these motors

    Is it TPS or load %?

    The other main tuning company has it as load % yet I havent found a valid load % PID so tuning VE is a crapshoot.

    Its going to take more than getting this axis swapped to run boost on a P10, Ive looked at it for years and there are only a few ways I can think of. 1 involved a different PCM and the other involved halving all the tables that are MAP referenced because once the PCM sees higher than 1Bar of pressure it throw a REP code.
