well a friend of mine has a turbo b16 and running 6 psi in a eg hatch and puts a cat on when it comes time to pass emission and after he is done he puts a high flow cat on and drives a whole year

if u want get a chip burned for ur car with no turbo and get another one when u get ur car tuned for the turbo

then for emission take the spring out of the wastegate
switch back to stock injectors
and shift at like 3000 rpm and put miles back on the ecu
go down and u will be able to pass emisions

put do this all the time for turbo obd2 car so it works it a proven trick i was going to have to do it on my ek but i ended up goin all motor


Call batlground or talk to Mr.Kidd they will be able to give u more info on it
