I'm thinking about going with a larger MAF, since I'm maxxed out at under 5k rpm's. I know others have done it, so obviously it's no big breakthrough

I'm a little nervous about tuning for it, but I'll log my data and take it slow. Any advice is appreciated.
I was originally going to use a ME7 MAF since I had a good used one at the shop. I made a short subharness to plug into the stock harness and discovered as I was looking at the pinout information that the ME7 MAF needed a 5v reference to operate. So my plan was to tap into the TPS to get 5 volts and send it to the MAF.....
I was getting ready to install this setup, when into the shop comes a '97 S90. Wow same size MAF as the ME7 and the S90 is M4.4, so it's plug-n-play (with the exception of tuning for it

) Found one on Ebay for $25, so the price was right. We'll see how it goes.....
