so i put a 90mm maf on my ls1 and now the engine light comes on and says bank 1 and 2 lean. obviously because of the extra air. my question is will the computer in time adjust for more fuel or whats the deal?

 

Probably not, when the lite comes on the computer has reached the programmed limit. You need to get the PCM tuned, also verify the MAF is connected properly and calibrated for your car.

 

haha im retarded i forgot to swap the actualy MAF and the housings so for a while i had an LT1 calibrated MAF on my LS1. i changed the sensors and its all good now. ..well the SES light went away. that probably hurt my gas mileage a bit.
