It could be a replica i think, bcoz it's cheap at rm260 and the mechanic said it's brand new, lol. I'm not sure what brand is it bcoz there's no hks logo, but looks like a ssqv, silver colour. At first the car was jerking when i'm boosting, but after the mechanic tighten the screw at the back, the jerking was gone. The sound flutters at light throttle and high pitch blow off sound at higher boost and rpm. http://www.hksusa.com/products/more.asp?id=792well are you using replica HKS SSQV BOV?
it might be the BOV leaking bro..
coz replica lifespan not really good if always high boost bro
Read somewhere that the atmospheric type may disturb the MAF sensor because it does not recirculate the boost back to the intake (hope my explanation is correct). Because of this, the fuel injected is momentarily in rich condition, so it says. Maybe that's explain why i smell fuel everytime the engine stalled after i release the gas paddle after boosting.
What bov are u and other sifus are using? Any bov brand or type that is recommended for this engine?
