Hi all, hope someone can help.
Got a ST cosworth about a month ago with standard engine with no mods, it was running ok on the way home boosting to 1 bar then upto 1.3bar on overboost.

Since then I have had a full service and new timing belt and ina tensonier,
when the garage did the cam belt they said the crank sensor gap was way to big so they set it to 0.8mm as the book says.

Now the car starts fine and runs ok when you feather the throttle upto boost but the boost is not stopping at the 1.0bar limit and when you push the throttle right down it goes past the boost limit of 1.3 bar and missfires.
any ideas guys
Dan
