RE: mass air flow
if you have 19lb inj. and maf cali. for 19 youre cool whether its a 65 or 70mm. but if you get 24 lb inj. later on youll have to have it recalibrated for the 24's.
the point is, it has to be matched with the injectors, no matter what size the tb is.

get a c n l if youre going to cjange injectors in the future. get the one with the 19lb cali. sensor. then youll have to get the new 30lb sensor when you get the 30's

RE: mass air flow
^^^either that or just get your inj's and MAF at the same time.
Just to clarify what was said above....Your MAF has electronics on it that must be calibrated for used w/ whatever size inj's your running. If you change inj's, you have to change sample tubes (C&L) or send it in to get it recalibrated (PMAS/Pro-M). The TB is mechanical and is independant of the MAF and inj's. The only thing you need to watch out for is getting a TB that's too big for your combo. Unless you've done an H/C/I swap or are running boost, you don't need a 70mm....bigger isn't always better.

RE: mass air flow
What about if your car is supercharged with a FMU. I know you've got to change the sampling tube in a C&L to match the injector size, but do you know if anything needs to be done to the FMU, if the injectors are changed?
Someone who acted like they knew there sh%t, said I would have to get a new plate in the FMU or get a new chip burned for the computer.
