I have a Autothority MAF. It came on a replacement motor that I bought. I like it and according to my dyno sheets, it does provide a hp/tq gain. If you go the MAF route, I suggest dynoing to get a air fuel reading. The off the shelf chips that come with the autot seem to run too rich. I had Steve W do a custom chip for mine and gain some additional hp but more importantly, got a better a/f mixture. I posted dyno sheets from my mods in this thread.

Here are the last dynos after Steve W tweeked the chip to improve the a/f mixture...it also gained a few hp. The lower line is the pre-tweeked dyno run.
