So, is the modded CP3 really worth the $$$?

I read on relentless diesel old website that the cp3 upgrade bumped the horsepower by 86hp. Your truck has more power available from the boxes, you just need the fuel supply to support it.

Is anyone running this?

RCCOX has the relentless kit. A very fast truck at the track and also turning some good numbers on the dyno. He has made over 800 at one of the national events.

if you can hold 30 psi you should be ok. the whole point to telling people that they needed to maintain that much pressure, is simply for the purpose of keeping fuel to the pump when it is trying to feed your rail/injectors adequate fuel, when at WOT.If your dropping fuel pressure your probably losing volume of fuel being fed to the CP3, therefore not supplying it with enough fuel to build pressure in the rail (hence running the rail dry).

When I get my Di procol rail pressure gauge in , I will find the sweet spot.
Thanks for everyones imput on this one.
