Is there anything complicated i should know about installing a Granatelli MAF Sensor, or is it just plug and play.

Plug and Play! (at least mine was back in '99) :thumbs:

sweet, that's what i thought

Other than the fact that they are a rip off and do nothing,you just plug it in.
FYI.I have one that was custom calibrated for a additional $125.00 + the $
350.00 i paid for it i will sell it cheap :jester

Very happy with mine...to each his own... :yesnod:

Hey Top gun,
Did you notice any surging or idle drop when comming to a stop?
Did you notice any performance gains?

Shane,
My idle is perfect, does not drop as I come to a stop. The reason I purchased the GMS MAF was to richen the mix under WOT. The MAF does its job. I have heard several complaints, but that goes for just about any mod. Some are happy and some are not.

I used to run over sized MAF ends...they led to nothing but problems. Very lean mixture...excessive detonation. Too much air passed the element without detection.

When I switched back to the stock ends and went for a test drive, the idle did just as you described...surged and nearly stalled when coming to a stop. Clearly needed an idle relearn...I put the aftermarket MAF ends back on and ordered the GMS MAF. Been happy ever since. I should still have the PCM tuned to optomize performance. :D

:iagree:

Likewise on my 97. I think many of the bolt ons were designed for the early 345HP LS1's and, may not work as well on the newer, 2000 and up, cars, IMHO.

I did find I had problems with the GMAF and the relocated MAT sensor mod. I removed the MAT and left the GMAF.

Like someone said, to each his own.

:iagree: however... my $0.02:
i purchased a granatelli MAFS, had for approx. 4-5 months and noticed no changes in idle, HP etc. So I sold it, got my $300.00 back and installed the stock back in but this time i simply removed the MAF screen.

I see you have a 2002. I did experience a SOTP improvement in my 97. I didn't get a dyno until much later and, those numbers, (see sig), show a substantial improvement over stock given the limited, bolt on only, mods.

A little more support for my theory that some mods work better on the earlier models that they were orginally designed for.

:cheers:

Remember also that GM put an updated MAF in 2001 and newer cars. I believe the stock unit (01-03 C5) may also be a larger diameter than the Granatelli unit.

I would save the money for something else :flag

My $.02

Might work if that is where the hold up is. Flow is fine with the stock one, need some head work then it warrant a different MAF. If you followed all of these so called mods you would have a thousand hp..... :rolleyes:

I have never had any luck with aftermarket MAFs and TBs. I run the stock TB MAF and Airbridge and seem to be getting enough air to the Engine. I'm not the fastest, but I can go out and play with most of them :D
