Anyone else out there throwing P0087s with a PPE on stage 1 and a duramaximizer (or other device) stack? Doesn't seem to happen on stage 2 or 3........

thats odd i thought the maximizer raised pressure?

fuel rail springs are weak-will not hold the proper amt of pressure try the shim kit or the race valve-other than that the only thing you can do is not turn the maximizer past 1/2 way

I have found that the Duramaximizer can only be turned up about 1/3 of a turn or it will set that code under WOT. It will also fall on its face, stacked, 90% of the time, as i'm sure you are aware.
I have found the perfect combo, imho, for stacking the Duramaximizer. I have been running it for about two weeks now and it Rips!! :ro)
P.M. me if anyone is curious.....

BTW, I have been doing extensive testing of the tuners in my sig. stacked (one at a time) with the Duramaximizer in different situations. (Not on a dyno)....real driving.

:)

My maximizer came with the shim kit so thats installed. I haven't really had this problem on other stages.

you can try the race valve to block off the refturn flow
and prob gonna need more supply to the inj pump
