Apexi Cat back
Blitz pod (I think).
all else is stock, bov, boost, pump, regulator, injectors, afm etc etc.
When I am driving along, and back off from the accelerator, if the revs are below say 2700rpm, instead of being a smooth sound and smooth deceleration, I get small popb and burbles from the exhaust.
if it is above this rev, it will be a smooth deceleration/sound all the way down from what ever rev I was at.. lets say 3500, to around 1500rpm, then burble and pop a few before I step on the clutch.
The car idles fine.
doesn't make any difference wether it's hot or cold weather or hot or cold engine.
I am getting 13L/100kms (got 399km and put in 52.3xL) with mixed freeway (100km/h) and suburban stop go traffic.
I don't have black shit all over the rear bumper so it's not running rich.
the Rb20's I've had have never done the above popping.
is it normal in RB25's?
this weekend the car will get new oil/filter and plugs as it's due for it's 5000km service but not sure if this will change anything.
or is it all normal?
