Hey all, this might sound strange but i have never actually sat in the car and revved the engine just for fun. when I did this I noticed that when I let off the accelerator there is a popping or backfire sound as the RPM's drop. is this normal? I only revved to 3 to 4K RPM and noticed it.
I did just install an RX catch can but I never did a rev before installing to compare to.
let me know your thoughts.

Re: rev pops
Thanks for the reply
I did a few more searches around the forum and found its something that happens with these engines, something to do with fuel mapping being a bit off on deceleration. I kinda like it so as long as its normal I wont worry.
