There is no MAF upgrade, and if youre going to do the Fast102, get the Nick Williams 102 TB. But like I said in your other post, the Fast102 is a waste of money. Just get your stock intake ported and pickup a VMAX ported throttle body, which is a questionable mod in itself. The intake parts on this engine are extremely efficient from the factory. The exhaust is where time and money should be spent.
