Ok i just installed a ppe dualfueler with a LBZ cp3/LBZ regulator, the Previous owner installed industrial injections "Bag of parts" on the cp3(LLY) in the valley. When i took the truck in To have the kit installed the tech hooked the truck ip to a scanner and discovered that the truck would start at 5000 psi and after 5seconds would climb 25000psi. If i turn off the lift pump it starts at 5000 and rises to 18000. now a few things come to mind #1 bad regulator #2 idiotic tuning 3# bad ECM(please no).
I have come to belive that it could be the tuning, im of the understanding that if it was a bad regulator the pump would imeadatly put out full rail pressure( please correct me if i am wrong) i would happily take a look at the regulator controll tables to pinpiont the problem but my V2 is having issues(wont comunicate with 3 different computers)
Now considering the fact that that the truck has dual fuelers one with a stock lbz and a modified lly pump would i be better off switching out the modified llyregulator for a stock lbz regulator? Or just leaving it as is and letting my tuner compensate for the mismatched regulators? Also since the valley cp3pump is modified(bag of parts) would any issues arise from switching to a stock LBZ or LLY regulator.
