I have a custom tune but need a new MAF. The current MAF is tuned for 42# injectors and is 80mm. If I buy a direct replacement will I need to get a new tune or is the MAF tuning in the chip? Any help is appreciated!

 

i would think it depends on the chip that u installed. most of the time a "chip" already has preset stuff for your stock sensors.

 

Its a diablo sport chip, the newer red chip i believe. Does that help?
