i have a cav turbo running phase 1 chips, eds intercooler, panel filter and stainless steel zorst. also using an apexi boost controller.
when the car is in high revs and boosting, i.e to overtake the car starts to judder and feel like its starting to miss, but when you change gear and the revs drop it seems to be fine again..
its really annoying and am not sure where to start!!
i was maybe thinking the actuator as it doesnt over-boost so well all the time, so sometimes it gets maybe 1.20 bar overboost othertimes it gets to 1.11 bar overboost then judders
any help is appreciated
