Yea probably not a recipe for sucess for a lasting 545rfe. I had a transgo shift kit and line pressure resistor for a 30 psi increase. My Ram was an 06, born with a 4.7 but swapped to a hemi with a cable operated throttle body run by a tuned 4.7 pcm. Kept taking OD clutches out of it running down the highway.

I don't feel the line pressure rose quickly enough for the sidewinder cammed, long tube, tuned 5.7.
