Why would an aftermarket fuel pump do anything to his current system if hes running a stock fpr? The pump wont pump more or less then what the fpr will regulate. He already has something to control the fuel and that is his stock fpr. No matter how many lph's of fuel that pump can pump the regulator will only regulate what it is set for. The only thing that beefy pump is doing right now is making sure that the fuel is getting to where it needs to go at a faster rate then his stock pump. Now granted, yes, he could have used his stock pump and been fine, but a 255 isnt going to hurt him in the least bit.
One problem I see is the base maps of the p72 which are for the gsr, they are NOT ment for the h22a. You need to resocket that ecu and chip it. Then run either hondata, uberdata, or even chrome with the correct h22 fuel maps. Or get yourself a p13. I myself am running chrome with the base map of a slightly modified h22a on my p28 and my h runs great.
But i dont see that as being the only problem he is having. I would like to hear which codes hes throwing before i even begin to speculate anymore.
