Ok would a truck mass air sensor fit on an ls1 car. If so would it give the same reading as the ls1 mass air. I saw at auto zone that the 5.3 and 6.0 truck motors take the same maf part 74-8411 while the ls1 cars take part 74-8308. The two sensors look visually the same but is there an internal calibration in them that makes them different.

You will probably have to rescale your MAF Table

So if I put one on with no tuning I would probably loose power

Maybe and maybe not.But I went to a 85 MAF when my car was stock without tune and I lost power.But all cars are different,You maybe fine.Let some of the more expert guys on here chime in....

Someone has to know the definite anwser to this

the car came a little rich from the factory
i got a 85mm MAF
and now the car is lean on idle and a little on part throttle
and gradually gets rich up to "pig rich" during WOT

its so bad
the car is faster during part throttle than during WOT

just have someone tune it after
you should make at least two hp.
two and a half if you take the screen out.

i also heard the MAF has something to do with auto trans line pressure.
