gm maf and stock maf

[jpmxrider489]

ok i tried searching but cant find a good reply.
my mods. i bought but not on the car yet
evo fmic
190 fuel pump
pte 550s
mhi small 16
safc2
1g bov recirc
fuel rail
ported o2 and turbo
catback exhaust

ok now for the question. i was loking at engine bay pics and i know noticed that most of the gm mafs are on the upper intercooler pipe. i also noticed that some are replacing the stock maf. i would like to get the big maf out of the way. thats is why i want to look into it.

1 what is the pros and cons
2 is it worth it.
3 is it something i should have
4 if my upic is bolted to the elbow would i have to cut it and put the gm maf in.
5 what is the main difference between stock maf and gm maf
if you guys can send any links just let me know.
im new to this whole tuning thing as if my car is my first dsm

BOV before GM MAF or after? - DSM Forums: Mitsubishi Eclipse, Plymouth Laser, and Eagle Talon Forum: DSMtalk.com this is a great start

ok i tried searching but cant find a good reply...

I just searched for "GM MAF" (with the quotes) and got 368 threads; and that is just here on DSMTuners. Not one of those threads answered your questions?

Tonnes of information gotta look.

1 what is the pros and cons

-The GM can read much more air accurately (although stock is more than enough for your setup)
-GM MAF allows BOV Vent to air

Cost and calibration issues are downsides.

2 is it worth it.

Not on your setup

3 is it something i should have

No, you don't need it

4 if my upic is bolted to the elbow would i have to cut it and put the gm maf in.

It needs to be in the upper IC pipe after the BOV...so look at your pipes and you'll know if you need to cut out a section and buy some couplers. 99% chance the answer is yes.

5 what is the main difference between stock maf and gm maf

The GM MAF uses a different type of sensor which works well in blow through applications, allowing the BOV to not be recirc'd. The GM MAF can read a lot more airflow than the stock MAF (About 50lbs/min vs 80lbs). Considering your setup is flowing <40lbs, the GM MAF wont really benefit you.

thanks bigbeans that was a help. thanks for the replies. my goal was < 400hp. one of the big reason i was looking into it was becuase it would take up less space.
