Ok.......and why it's not a good idea for the E and the Vortech ????
Sorry but i'm lost a little bit...
A MAF sensor is just that, a sensor, a meter, is not a performance item (as Jet performance makes you think) and as many things in this, bigger is not always better, as a meter, you need it to have enough range maintaining resolution.
You have a MAFia because the stock sensor does not provides enough range, it will peg quite soon with big airflow situations, it is an extender, is just there to give the stock sensor more range.
A modified aftermarket sensor will have more range (in this case will show less voltage with the same airflow) so you will have range, but by doing this, you lose resolution (same airflow changes reflect lower voltage changes).
Actual final range of a sensor depends on its housing size, it meters a small fraction of the cross section of the housing pipe, the bigger the housing, more total airflow with the same readout, gaining range.
So choosing a correct meter is important because if you go too big you lose too much resolution and can get into issues, if too small, it will peg.
You current V3 housing is close to a 4" OD housing, the stock sensor would peg around the 400rwhp, with a a MAFia you can make it go around the 6xx, an HPX could get you over the 8xx-1000probably, an HPX-E about around the 1200+rwhp, (all these are very gross estimations), ProM and a newer BA5000 around that too. So you will be using only half of the sensor range with very poor resolution that can get into issues.
So you can not just take an aftermarket meter as a performance or isolated item, need to estimate airflow and consider housing size (among other stuff you dont need get into being draw thru)
