i also have to add to my exhaust sounds crazy over 3600rpm where my pops and bangs kicks in which is applied to my tune

this is not my Evo ( this is not even a X) but you get the idea.

 

Rob that was amazing. Is that an anti lag system? I would love to have something like that on my car.

 

Mine does it. (Not willingly, i just need a tune badly)

Just tune your car pig rich. I get about 12 mpg but the flames are sweet

 

its not, does however something similar by sound. Not a rich tune causing this. This is tuned purposely, if you release the throttle it will continuously pop and bang. sometimes ridiculously loud. that is why mine stops under 3600 rpm .

Depends how good your tuner and ecu ( the X has a great one the pops more and more likely sounds like an ALS)
here is a X way it sounds with a faster ecu so the pops are more frequent.
