Finalizing the list!

It's almost time to order all of the stuff for the supercharger, and I only need a little info on the last piece. I've decided to get the Vortech S-trim with Ford Racing 42# injectors, a Kirban AFPR, a Walbro 255 lph in tank fp, and I just need help with my maf. I know I need one that's calibrated for 42# injectors, but I'm a little confused about the size. I keep reading 80mm, 90mm, but I don't know what's right for me. The car has the full exhaust listed in the sig, but that's all for upgrades. The air intake system is stock. What size MAF sensor and what brand do you suggest? If you could post a link that would be helpful too. Thanks a lot guys, and this is going on a dyno the same day it gets finished (the performance shop putting it on has one) so I'll get some figures up when she is all said and done

Well... in addition I know that pro-m went out of business, and that is who I was going to originally purchase one from, but I'm not sure if they are still available anywhere. Any help guys?

Wow! I never realized how expensive an aftermarket MAF is! I sent them an e-mail with an inquiry dealing with my application and was searching through their product list. I see 2 MAF for S/C setups, but they both say for S/C and power pipe. Is a power pipe a term for an aftermarket air intake system or is it something else?
