Bumped the boost up to 12 lbs with the p1. Hp is showing 105% duty cycle at 4800 rpm with the 42lb injectors. Should have gone 60 like some of you have said. It sucks to be wrong!

 

what sucks is as soon as you get your injectors situated you'll be out of pump next ...lol never ending battle !!

 

Sucks bro, sorry to hear it.

 

Buy my 60's lol

 

some 60's will be a great injector for your setup. next i would do 255 if you dont already

 

Pump is next brotha!!! So at any rate how does 12 psi feel up untill that??

 

Are these in the classifieds?? I didn't see anything...

 

I've got an intank 255. Next it looks like I'm gonna need a boostapump. 12lbs is max I'm going on that stock engine. Feels real strong for an ol heavy *** Denali!lol My buddy with an SSS said it was heavier than his truck. Said he could tell by the way his lift sounded when we did the exhaust. Don't think it's near as fast as manglers after watching the vid.

 

Are now

 

Save your money on the boostapump and pick up some 60's. With the 255 intank, 60's should be fine at 12 lbs. You can buy a used set of 60's for around $300 and sell you 42's to cover a chunk of it.

There just happens to be a set for sale at this momment courtesy of 1BADAZZSS...
