Hey All

I installed a Blitz DD Blow off valve on my R34 yesterday, and now the exhaust periodically back fires usually only when changing from 1st to second, but also can happen when just reving the car in neutral when it returns to idle.

I have a feeling it is because the stock BOV is a recirc where as this one is not and therefore the amount of boost pressure.

Anyone had this before?

and

Any ideas on how to fix the back fire issue?

Cheers Ed

Plumb it back if you can.......AFM equipped cars dont like atmo venting bovs.......and yes that is a common problem with atmo bovs on skylines.

Either plumb it back like I mentioned earlier....or if you cant then put the stock bov on and sell your one and buy one that can be plumbed back.

yeah i thought that might be the case, thought it would be ok though as my mate had one without issue, know of any changes i can make with the AFM? i am about to put a apexi power intake on so i have to dabble in that area anyway.
