I have a truck with the following mods-
Built Short Block, Stage 2 cams and springs, E-fan, Cobra WP,Full exhaust, Ported eaton, CAI, 8 pound lower,E-Fan,Cobra WP, Accufab TB, dual 255 fuel pumps, JDM heat exchanger, NX wet kit.
I called JDM today to get a custom chip programed for my truck. Jim would not even sell me the chip unless I got 55 pound injectors, and a 92mm Pro M mass air. He also said that with this set up I would likely see 525 HP with out the Nitrous.

My question is how many big hp people are running 55 pound injectors and the Pro M 92 mm mass air? I am asking because before todays conversation with Jim i didnt know of anyone running a Pro M mass air. I did however hear of people pegging the stock MAF. Is this 92 mm Pro M that great.

Thanks
Zach

 

I would either get the 50's or 55 lb injectors if you plan on spraying...... I have 50's and I have no problems
I don't know much about the Pro M mass air so I am not gonna comment on it.......

 

the problem w/ the setup you have is you are going to peg the mass air at 5 volts. when this happens the sensor goes into default and it does not read all the air going into the engine, it it can't read the air it can't supply the right amount of fuel.
no fuel = kaboom!

the pro-m is a very good unit not only is it calibrated for that amount of air it also offers less restriction because there is no huge vein running across the sensor.
and w/ that amout of power you should put the 55lbs. injectors.
hope this clears some things up.
