not with those mods.

you pick up a bigmaf when you run out of maf headroom. not before, imo.

exactly what Ride said, Without EM you will not be able to use the big MAF as it will make your car run very lean. I am running a sr-50 on my sti and a bunch of intake work. I see consistant 4.9v from the maf and on a cool day I might touch 5.0v. I am at the borderline at this point if I run any more boost I will have to get a larger MAF for more head room.

On another note, I am not a big fan of the Perrin MAF as there is not enough piping b4 the MAF to get a smooth flow through the sensor. Also sourcing air from the engine compartment is less than idea. I personally run the APS 65mm intake and have a 70mm standing by for the day I decide to see what the block will handle.
