Hi guys I recently had vrsf down ***** fitted and since then, only occasionally I get a pop sound from the I take area of the car. I was told it may be backfiring however to me it sounds like it's coming from the intake. It's quiet a muffled PPP but loud.

Any ideas?

Is your charge pipe in good shape?

Sounds like backfire. Could be many things.

Check your AFR, leaking injectors, but my guess is that you might have a tiny exhaust leak from the d0wnp1pes gaskets.
