Ok, it's been a while but I took my car in today to RE Customs. Fixed rocker cover leaks and fixed my "cut out" problem. It was fuel cut as my AVC-R was spiking.
Ray chucked it on the dyno and had it sorted in about 20 mins, if that. Nothing wrong with my turbo, no oil in cooler piping, car runs fine, timing is spot on, running max 12psi.
So moral of the story is this last workshop I had gone to talked abosolute BS basically... My car made a nice 168.9rwkw. I was quite pleased with that result. The line in green was the last AVC-R settings, boost control issues, not a very smooth curve. Blue line is Ray's work. A much smoother curve. Car drives like a dream again and boost comes on nice and strong now, my love of driving my car is back!
I'll definently be going back to RE again, great work, great price and excellent service, hard to find a workshop like that.
