mass air sensor

[z9_87]

I know that the mass air sensors are supposed to be calibrated to the injectors, but how big of difference does it make? Also would putting a too small tube that the meter sits on also effect power alot?

It makes a HUGE difference. Calibrated meter or custom tuned chip. Take your pick or pick both.

How big of housing that the sensor sits on would you reccomend? 70, 73, 76? Also do you thing the throttle body is big enough for my combo in my sig?
