    nope rpms shouldn change on which motor he has but if the tires have wear and I think it can fluctuate a little between a 4r70 and 4r100 but not sure.

    I have a 5.4 but I'll have to wait and test tomorrow. Unfortunately I don't have a tuner (yet) so I won't know an exact number but I'll be able to ball park.
