This feels odd,car starts,runs,idles perfectly.Since i've had the car there is an odd feeling when accelerating just off boost,it feels like the car isn't going forward as quickly as the accelerator's going down,like driving through a wall of treacle,or your towing something heavy??
New plugs,filter etc.CAR NEVER STUTTERS,JUST DOESN'T PULL,THEN WHEN THE BOOST COMES ON IT COMES ON SMOOTHLY WITH A REAL HIT AND HOLDS THE BOOST PERFECTLY AT 1.2 BAr,brakes all renewed so no dragging,fuel consumption is horrendous,old plugs that came out were perfect sandy brown colour.

Yes standard turbo.Car is fitted with an aftermarket fuel pressure regulator,someone said this might cause issues,depending on the exploits of previous owners ofcourse!

Plugs on a modern fuel injected cat equipped car shouldn't be sandy brown. That's what plugs on old carb engines used to look like. They should be nearly white.

So let's review. Fuel consumption terrible, plugs rich, not running right. Could any part of the fuel system have been fecked about in some sort of idiotic aim to richen things up and need changing back to stock? I'm stumped, it's a real puzzler! Gonna take someone much smarter than me to figure this one out.
Glad who ever done this to the car has you so puzzled!
