Looking For The Right Maf Sensor For Fox 5.0

way too much injector IMO but that's what you have. The LMAF will work, so will most Pro M's You are getting it tuned so it doesn't matter what the MAF is calibrated for.

Probably a really low duty cycle (if I understand injector PWM correctly). What do you have planned? I am running 30lb.ers on my 347 and have plenty of fuel.

34's? Never heard of that size but anyway...with a tune the injecters will be fine.

If you purchase a new Mass Air from ProM or PMas, you can get the 30 point transfer curve from them. All your tuner has to do is input that curve into the calibration. It should be close enough that he shouldn't have to mess with it after that. And if he does, it won't be much.

your injectors are fine you won't have any issues there, they are most likely the 36lb injectors and some people refer to them at 34s because thats what they flow at 39psi which ford uses

if your going to buy a maf get the best money can buy, a pmas hpx-e slot maf in a 3" pipe, the whole she-bang can be had out the door for $200 including the pigtail

be sure you get with a tuner that will give you a tune update when you throw boost at the ride, the maf will support it, if you get bigger injectors now (perhaps siemens deka 80s from poweraddersolutions >> hint hint) then you can have the tune dialed in now so when you throw boost at it later you won't have to get it retuned, just make sure you let the tuner know so he can setup the tune correctly

be sure before you take your vehicle to get tuned that its actually ready to be tuned, thats a common mistake made often, this will give you all the info you need
