I just picked up my new to me 200t this Sat. The boost is getting as high as 1.8 bar and shuting off the fuel. The end cap is still there on the wastegate, and the bolts holding the cap look untouched. Any ideas or remedies? The car is a late 88 built (12/88) with the MAC 14 computer. I am afraid to modify the ecu as I may cook the slushbox. TIA Matthew Twigg 1987 4kcsq 1989 200t
