I have a MY98 and am getting lots of popping on deceleration, mods include a large stainless system and down pipe, K&N 57i and Blitz dump valve, is this normal? and does anyone know how to adjust the idle setting on the Supersound dump valve?

 

yes its normal good int it ?????? alan.

 

Very normal thats what makes slowing down fun

Sorry can't help on the dump valve query.

 

hi m8 i also get the pop but i have a plug leed going and she has started poping different whe she normaly wouldnt
i think it is a leed going could be wrong like

 

I have 93wrx full s/s,dump valve,direct induction and i get no popping at all ? Why is this how can i make it pop cos i love that sound.

 

do you have a re-circ d/v or a vta. the vta's tend to pop more because they over fuel a bit.

 

I do have a vta dump valve but still no pops
