Just kinda curious on everyone's experience here...seems as if one person is hitting 550-600rwhp on one and big boost, then i read another post about one maxing out at like 450rwhp and 7-8 psi.. ? I figure if magnacharger and some other manufacturers trust them enough to not supply in a kit they must be pretty stout...

Whats your experience??

 

mine was maxed out on 7lbs of boost and my maf was getting close to being maxed. I went ahead and put a walbro 450 100lb injectors and ordered a 3 bar map so i can get a speed density. if your gunna go more than 10lbs might as well do the upgrades before u get tuned

 

From what I have seen, heard and experienced. They are good to 550-600whp 12psi ish my non flex pump was good to 5psi that was all.

 

Well I had a big walbro in my old 2003 5.3 and 60#s running 15 psi...but im about to throw a small cam and heads on my ccsb.. and thought about a p1sc. Done the turbo route years ago and want a more bolt on and done approach these days lol.

 

mine in the '11 is holding up great

 

Guess i can only try and see what happens....maybe ill be one of the lucky ones?

 

I think u will be fine I think more than anything my flex fuel injectors where being maxed out not necessarily the pump I just changed it to avoid problems with higher boost

 

OHHH ok....yeah i definitely was going to change injectors...just didnt want to have to put a pump in it....lol

 

I have the stock Flex pump with black ops 60 lbers and 12 psi. Works fine

 

Thats the route i was going Choda, stock Flex pump..60's and about 10-12 psi on a maggie or p1sc.
