Im running 2 of Reds chips. The 93 street chip and the 107 race chip. I would think the car could run a little more rich with both screen in the MAF. I think running both screens in the MAF would restrict the airflow a little bit but not too much to notice.It still should run good though with the screens in it.
Red has always told me the first thing to do before installing a chip on a stock car is remove one of the MAF screens.
The times run in my sig. are with a stock MAF with 1 screen removed and reds 107 race chip at 24 psi boost.
