Exhuast Poping Nosie On Deaccleation

[Scottie]

hey guys the popping on de acceleration has been getting worse for awhile and last night at the drags made it ten times worse. Orginally i thought the cat had shit itself but i had it on a hoist today and the exhuast is all good. And there appears to be no exhaust leaks and no intake leaks and it is holding boost what can course this poping. It appears to be down on power as well. I am hoping that a spike to 16 psi last night down the strip hasnt affected the stock turbo.

its normal to have abit of popping, my pops it ass off normally

If you think its excessive or getting worse i would check for intake leaks, just simple things like tight hose clamps and all vacuum hoses are on tight with cable ties. What bov are you running? Could that be leaking slightly?

Also what ecu are you running? stock or tuned?

if the turbo is still boosting fine without funny noises it should be ok, a quick 16psi spike wont hurt it, continous high boost will.

Also remember it is summer now, turbo cars hate the heat so its normal to have a significant drop in power during the day aswell.

Love my pops. Sounds mad.

[Scottie]

lol yeah its good but mine sounds pritty bad more like a old shit box back firing but instead its poping lol i will check the cooler pipes and extra tomorrow. It has a stock ecu but its been retuned by toshi and i am running a stock bov

[BeEnAr]

it's just unburnt fuel dude, don't worry bout it

check your plugs for fouling,

my gtr runs pretty rich, and starts backfiring after about 2 months, especially in summer, the plugs will soot up, i just clean them and problem gone........

hope this works for ya

disable your anti-lag

I have it... I love it! sometimes blows a mean flame too

[Scottie]

i will check the plugs there only alittle bit over a month old and the o2 sensor is good its not old at all and tested it a couple of weeks ago and i would mind the pop if it wasnt to excessive but it is quiet bad

[DRD-00F]

what ECU are you running and how's the tune?

it normally happens when it's too rich...

[Guilt-Toy]

disable your anti-lag

I have it... I love it! sometimes blows a mean flame too

lol.. antilag? lol wait till power cruise

I had a problem similar to this turned out to be a leaking o-ring in an injector.

however it can be a number of things a small vacume leak, plugs, afm, 02 sensor. since plugs and 02 sensor are newish i would look at clean afm, then change fuel filter (never know) then look for any fuel leaks

Just the tune is a bit rich id imagine

Mine does it more and more as its nearing a service due to plugs etc.

Its quite a lot at present being a service is gonna happen soon

[Ultimategtr]

fowled plugs. what plugs u running? just clean em up.

[Scottie]

tune is ok i was on the dyno not long ago and it was all good. plugs are bcpr7es re gaped to 0.8 of a mm

[donkey]

have you tryed the plug clean yet? just about to do mine
