I can easily hit 25,600psi at part throttle with Smarty and Quad X2 race stacked but pressure drops fairly quickly to 19-20,000psi @ WOT. Is it better to try and run max settings on the Smarty and low settings on the Quad to maintain decent pressure or lower settings on the Smarty and Max out the Quad X2 race? Or run both on high settings and not care if rail pressure drops to 17,000psi @ WOT? I really want to get a stage 2 CP3 but I can't get ahold of anyone at Floor It to get some prices. With a DIY CP3 mod what pressure should I be looking to hold for best performance @ WOT. Thanks for any advice, Tom J.

 

Keeping it above 20k is optimal. As for the upper limit, opinions will vary. I try to have mine at 26k since it will only read 26.5k. If it pegs the gauge you don't really know what you're running. Could be 27k. Could be 30k.

 

Mark says you need optimal minimum of 23.5 at wot!

 

only a low minimum? What's don say short bursts are allowable up to? I thought I read that the you don't want more than 26 when pegged goin down the track.
