How do you know it's down on power ?
Sorry may sound like a stupid question but bit more info would help like did it just all of a sudden become under powered or did you buy it and it's not what you expected ...?
its very hard to describe! when i get up in the rpm gets very sluggish and the turbo timer starts hopping?
the service was done when i got it few mouths back will be doing full service in next week or so...
Turbo timer will have nothing to do with it, it's wired to let the engine run after you take out the key that's it. Not wired to or connected to the turbo in any way
