Has anyone used Ralph & Johns shop in Brooklyn NY to have their Jeep tuned? I got their number off the Diablo website and scheduled an appointment for next Wednesday ... The guy told me it would be $150 an hour to tune on the dyno and it would take 2 hours to tune my 5.7 Hemi ...and I should be looking at 40 more horsepower on top of my Diablo tune... So any feeback on this is greatly appreciated guys

I would do some research as to them tuning HEMI's.

Let me see what I can find.


EDIT: I wouldnt be hesitant to try these guys out. Seem to be legit. I got to check this place out.

Thanks bro!

Checked their website out. They have done Fords, Chevy's and Mopars. They are also authorized on the Diablo website. As long as they have a AWD dyno, do it.
