Is overboost protection like a rapid fluttering sensation sorta juddering? Only in my last T5 it sorta cut then came back, but in the present t5 its like a juddering. It has a rica 304 remap. I have tried fitting an MBC today it is turned down to minimum and it is better but still seems to overboost (if thats what it is doing). I am not an expert in these matters by any stretch. Any help would be appreciated. I was thinking that the wastegate is staying shut too much could it be an actuator fault?? HELP!
