Actuator!!! Where is it, and is it safe to 'give it a few turns' to improve boost???
Just a thought

 

I can tell you where it is but can't say whether it's safe to play with it or not. It should be under the turbo heat sheild on left hand side of the intercooler as you face the engine. I wouldn't advise playing with it unless you know what you're doing and have a boost gauge and knocklink fitted.

 

Reeto Paul, I think I'll leave it alone! 220BHP will have to do for now
