I am trying to get rid of a low RPM stumble. With only 200 HP the 4" seemed like overkill and with sudden opening of the throttle bodies the MAF seemed to not read accurately. Makes everyday driving aggravating. I have adjusted values all over the place with no real change. Was going to try a smaller MAF that could read lower flows better. Any other ideas? can the 3" MAF be modified to work? This is for a 071 ECU.
Thanks,
Michael
