Or is it that extending the main injectors' on time isn't enough to get the AFR below 13:1 because they're too small? Does the PC Pro work off of a MAP sensor? |
PC-Pro I think works off RPM.

Yes he is running out of main injectors. The MP62 with the pulley he provides is good for 200 whp minimum, realistically 205-210. There's not 200 whp worth of fuel in the stock fuel system. There's maybe 190 in a NB, 170 in a NA8, and 160 in a NA6 if the injectors are all fresh and the pump is strong.
I don't see what would be wrong with a PCP based system, as a PNP solution, if used with pulleys that made less boost. |

He uses an M62 for the coldside?

His only so called "innovation" is, running a 5th injector and along with it selling a second PCPro piggyback (because the first one can't handle more outputs) for another $400 and calling it with tricky marketing name E-Cool intercooler instead of just "extra injector controlled by PCPro" (like pretty much everyone else using a 5th injector does). He got CARB EO too. Later contrary to his initial claims about not needing timing control he figured out he might need such and now testing PCPro timing cards from Moss. So if you're running his stuff you might end up running 3 piggybacks for maybe $1K or over. For that much money on the market you can find piggybacks which are much cheaper and can do much more in a single box... |
