Your best bet with modifications is to have a long-term goal. People start picking pieces, then changing directions down the road, then end up with useless parts. Basically I would pick your horsepower goal first, then the mods you will be taking to get there. Also consider how you want it to drive on the street or if it is going to be a trailor track queen. Also, it is important to know operating RPM range.
For the MAF, I would choose that later. Due to the fact that you need to pick an appropriate fuel injector size for your ultimate goal, no need in getting the wrong calibration when it comes time to order it. A 65mm is about as big as you want to go for stock induction components. If you ever start hitting towards the 350 hp level a 70mm would be an excellent choice. Obviously though, the bigger things are, then the extra power must also be present to work correctly. Accufab is a very high quality piece, I wouldn't both with a Granatelli piece. As sad as it is, GMS products are hardly their own. they contract out to other companies to make their stuff then they just re-sell them off as their own for a very jacked-up price.
