FPR kit is safe with flash?

To all that have flashed there PCM... Are you running joe.P's FPR kit as well? Just curious to see if the FPR kit has helped even with the flash.
 
I've had the fpr kit on pretty much since day one. I have not taken it off since. So I dunnno how it'll affect performance wise, but I've happy with my car now and it's still rich as hell, so it's staying on.
 
But what if we wanted to turn our boost up to 10psi? Wouldn't the FPR combined with the flash run the car too lean and run the risk of inflicting unspeakable harm to our delicate little engine?
 
ummm...ok. How about boosting to 10psi WITH the flash but WITHOUT the FPR. (With colder plugs of course)

Think there will be problems with that?
 
that's your chance to take. the professionals at mazda said no more than 9 psi, that includes where you spike. but there's a couple people that are boosting >10psi WITH the flash (some are at 12) and haven't had problems yet. so it's your choice.....take a chance and up the boost or keep your motor safe and boost 9.
 
My FPR and MBC should be here sometime in the next week...... ive had the flash and plan to install the MBC...... should I go ahead and put in the FPR as well?

Hi, where did you hear that 9 psi was max? I'm not doubting you, just curious...
