Backfiring & Stuttering

[Demi]

LOL - I say that because the ONLY reason to do a VTA on the MS3 is because you like the sound and/or want other people to hear the sound and don't really care how it hurts the car....AKA Road Thug where the bling bling is more important.

Or you could be like me and run VTA because you pulled out you stock bypass valve and the military movers pack it and your HKS recuirc kit!!!!! Sigh.......true story. Thank god they missed my BOV.
But I do got me some street thug in my viens as I love the sound. LOL.

what you need is the one step colder plugs gapped at .030 and you wont have this problem anymore... before i put mine in i could never even give it HALF throttle without it popping and banging and all that good stuff. it runs really good now.. even with the mods i got ms cai, 2nd cat delete, atp bcd, turboxs bc,hks bov, shifter bushing, im peaking at 21psi and holding at 17 an 18psi, stretched coil mod that didnt help me at all, running in 12 and below temps out side and i still dont get popping and stuff anymore..

21 psi on the stock turbo?? That can't be good
