Hi guys. So I've had this little issue since I replaced my faulty MAF sensor with a sparkly new one. I get the feeling it may have something to do with having the N249 bypass but I'm hoping someone can enlighten me more. When accelerating hard (noticable from about 3k upwards) and lift off the accelerator, obviously I hear the DV kick in and divert pressure, but I get a little acceleration surge. This has the effect of feeling a bit like a single kangaroo jump for want of a better explanation. Any ideas? Spec in the sig.
