I am getting backfire when i switch gears on higher levels of boost. I know this is probably due to the hks bov i just recently installed, as i wasnt having this issue previously. Just wondering what damage the backfire is doing to my car? any help would be great

maybe an air leak screwing around with the AFM reading?
or even AFM itself??

Definately BOV.
Uses a tad more fuel, makes a bit of soot.

hmm ill have to check that. It wasnt backfiring though previous to the bov. ive had a verso tune, but since then ive put on the bov and boost controller. would i need a re-tune

Its Recommended that you get a re-tune now that the BOV and boost controller have been put back on.

It may fix your backfire issue.

cheers, but as far as damage to my car having backfire, is there any need for concern?

I have an SSQV on my sti, mine never backfires between gears. Checked for any vacuum leaks?

Won't damage anything.. it's just unburnt fuel which ignites in the exhaust
