hey XSracinggt do I have to buy new mass air . And dew anyone make a 75mm and do you know how big I can go before losing power?

 

If your gunna put 24#'s Yeah youll need a new mass air sensors else itll run like ****. You could get yours recalibrated for 24#'s but if you buy a new one you can also get a bigger one. C&L I know makes a 75 or 76mm, also I think Ive seen 80s but Im not sure if it was for a stang. I dunno if how big you can go but a 76 would prolly do the trick.

 

ive got a pro-m mafs and its 80mm and a 75 mm tb. yeah, if you want the best power out of your combo, get a bigger mafs. Make sure its bigger that your throttle body tho. Get a 75 mm mafs, and a 70 mm tb. Thats a great combo I have heard from the guys that use it. You could go with a 80 mafs and even a 75 tb if your intake has that size opening. My Street heat tfs intake has a 75mm opening, so i am going with the biggest I can get. You will have to have the mafs recalibrated, just tell them on the phone when you order it what size injectors you are running and they will make sure they get you the right calibration. you could go with either pro- m or C&L. No prob on the help. Glad to help you out. Hope the car runs great when you get all this on there.
