88 5.0 mass air conversion

You guys got lots of info please try this one. I run a rebuilt 88 roller motor, E cam, E cast heads, roller rockers, 19 lb injectors ,shorty headers, 2.1/4 pipes, a9p computer, with mass air converion, with cold air induction. AOD trans with wide ratio gears and B&M shift kit.I don,t think Im getting the most otta the motor . My mass air is a 55-mm ,can you recomend a better unit ,maybe a 70-mm from a 93 cobra? money is light so a used unit fits my bugget if it will work? Thank you all ... Thewanderer

I'd suggest looking on ebay for a used Pro-M unit. A 75mm will be fine for your combo. Personally i'd stay away from the other maf units that require you to change sampling tubes. Decide now if you are going to go to a larger combo in the near future, because if you are planning on doing a supercharger, or similar you will need larger injectors.
MAF meters need to be calibrated to whatever injectors you'll be using, so for right now you need to get one calibrated for 19lb injectors, but if you decide to go to 24-36lb units in the future you'll have to get your MAF recalibrated or buy a new one.
