engine pop and bang with flamethrower ??

[yellowvette]

Hi I just buy vintage red FD3S from ryan and have some questions on it !
car run fine and good on boost no misfire or boost pressure loose, run good and do the 330BHP !!
but when I decellerate slowly the car pop and bang really loud like a kalashnikov or one canon shot throught the apexi exhaust always between 2000/2500 rpm....when I decellerate in one time (just put of the foot of the accelerator pedal) car decellerate normaly with little pop sometimes but really less shotgun fire !
and on the highway I do really big flames (50/70cm) throught the exhaust !
here is my setup

- Bilstein coilovers
- HKS SSQV
- 6000k HIDS
- Apexi GT exhaust
- Silenced midpipe
- FEED downpipe (wrapped)
- Border Racing induction
- TRUST intercooler
- Custom ducting
- 850 primaries
- Walbro 255
- Aeromotive stylee FPR
- Ported wastegate
- Apexi PFC

Yeah don\'t worry flames and bangs are part of the rotary appeal

Plus you can ask someone kindly not to drive up your rear bumper with a nice pop and flame

Sometimes all you get to hear is the fuel igniting in the exhaust without any flames, always great at night
