Okay,
I have been shopping for MAF Sensors I found 3 different ones on the GTM site, I am sure there are probably others out there but I haven't found them.... The 3 they had listed are UpRev, GTM, PMASS. Below is some info on each. I am trying to get the most reliable and programmable by UpRev. I have done some searches on the forum but only found info on UpRev MAFs. Please someone take me to school !!!!

PMASS PREFORAMCE MAF SENSOR
DESCRIPTION:
Probably the most versatile performance mass air sensor on the market. Complete with the HPX software tool the possibilities are pretty much limitless.
Capable of supporting over 1000WHP, Will never peg, Can be used in ln most any intake system configuration, Great for blow thru or draw thru systems, Never needs re-calibrating, No more need for a conventional mass air sensor assembly, this sensor simply drops into your existing intake plumbing, Small footprint allows for exceptional airflow, Every sensor is repeatable within O.E.M. spec, Software transfer-function generating tool included for using the HPX in different tubing, Limited Lifetime Warranty.
*Doesn't say if its program compatible with UpRev, I have seen a lot of these on Fords.

GTM PERFORMANCE MAF
GTM Performance Engineering is proud to present our custom calibrated high performance MAF sensor. After tuning hundreds of cars ranging from mild naturally aspirated bolt on Nissans and Infinitis to all out 1000hp Twin Turbo cars, we felt there was a need for a sensor that read more airflow without losing the resolution needed to have a stable idle, good cruise and low load engine operation. By adjusting the design of the MAF sensor, we are able to offer extended range for up to 190% more airflow than the stock sensors. This development translates into having a 1000hp car that starts up every time and can be driven normally on the street.

UPREV MAF GT
UpRev MAF GT sensor will read almost 180% the air flow range of the factory sensor while allowing stable idle air flow measurements. If you have a Nissan or Infiniti vehicle that you're adding Forced Induction to, you will need this upgraded MAF Sensor. We've worked for many years to offer a MAF sensor that we can put our name on. Finally we have the right sensor. Years of being the only manufacturer to support Forced Induction properly on the Nissan vehicles using the factory ECU has allowed us to understand what our customers need and this is the product we've brought to market.
UpRev MAF GT sensor works on a wide range of current and older model Nissan and Infiniti vehicles. The diameter of the MAF tube changes, so and exact HP or Flow range cannot be stated for each vehicle. Nissan has generally matched the Factory MAF tube to reach the 4.9v range at 130% over the factory HP. If you're adding Forced Induction you will be out flowing the factory MAF sensor. We've designed this MAF sensor to meet those needs.
I got all this info off the GTM site. I have no experience with any of these so input is requested. My build is a Stillen SC, very common kit how ever I have swapped out the impeller with a 928. The out put on the SC is small so the air will be traveling as fast or faster than a turbo set up. So I am looking for a set of reliable MAFs.
1st Question: Are the PMASS & GTM MAFs programmable with UpRev Tune?
2nd Question: Which is more reliable?
3rd Question: What are you using?
Thanks
