looking to get info on changing pressure boxes. i run the dr. p box currently and was wondering if any of you have compared this box with the mp-8? any info comparing the two is greatly appreciated. i understand the difference between the two, has anyone seen a power increase when changing.
thanks.

I don't have any experience with Dr. P or the MP8 but I see no reason to fool with another pressure box. You already have pressure via the Dr. P and/or Smarty, those two should give you enough pressure to grenade any injector that gets on your bad side.

I have Smarty and VA 3.1 and to be honest I usually run Smarty with no RP increase and only occasionally use the VA. Dont get me wrong I really like the way the truck behaves with aggressive pressure but I have had injector troubles in the past so I am pretty conservative with the pressure in my day to day driving.

Don M. "The injector guru" has repeatedly posted on the negative effects of too much pressure. He fixed mine once, I would rather not have him do it again.
