definitely a rev limiter?

boost leak test? sometimes a small boost leak feels like you hit a brick wall.

try cleaning your MAF that has been known to cause a similar issue.

i was thinking that, but mine sounded like rapid backfiring, not a rev limiter...

whats your A/F when its braking up ?
whats your plug gap?
