it is all about timing as somebody said above. .i believe the idea is to back the timing in the low load zone to let the Fuel/Air mixture burn in the exhaust instead of combustion chamber. You have to make sure that you dont have the stock exhaust otherwise you may damage it.
be-careful with that. it is not something recommended.
ok, so what about the soft rev limiter? Let's say I have my limiter set to 3500rpm, can I disable the ignition or fuel cut for the rev limiter causing the
backfire or antilag? This way when hitting the rev limiter that's set it can do the popping then.
