Quoting LIV4PSI:
GM MAF isn't speed density, it is blow through. Speed density is no MAF, blowthrough is moving the MAF post intake to the intercooler piping.You are mixing the two together.
You should just need a MAP sensor, an IAT sensor, an adapter harness, and new intake. Oh, and a new tune of course
If you actually want to go blowthrough, I have a GM MAF, couplers, intake, and MAF translator for sale
Lmao i feel like a dumb ass. i am not quite sure why i was thinking i needed the GM MAf for speed density, i think the gm cable and speed density cable was mixing me up thinking i needed it. i was trying to think how i had my old car setup. i just had identical twin girls give me a break, my mind does not think the same anymore!!!
even easier now. just need the cable and map sensor. they have the map on fleabay for like $25, i have my old 2g TB elbow still with the IAT installed along with a brand new intake setup made for a vr4/speed density.
