Back from the Dyno - Need Advice.

Thanks for the input Hammer. I have 30 pound injectors. I plan on having the customer tune once the new chip goes in, I just have to schedule "the tuner" when he is in town. I guess the brains behind the tune doesn't reside in little old Jacksonville, so I've gotta wait until he shows up, which should be by the end of the month. Another stupid question, what's the MAF (I know what the MAS is, but MAF?). Thanks!
