I have a standard 2.5 exhaust on my 3b coupe with no cats, running rs2 exhaust manifold plus turbo and injectors,with standard air box and inter cooler ,what if any advantage is there in fitting SS 2.75 turbo back system including sports cat before I get it remapped.

Hi mate turbo has been rebuilt and is back on the car.
I see you are still having problems with your S6. This is a long shot but has the cam belt been replaced in the last year or two, if it has then there is a chance that it was not torqued up sufficiently allowing the key way to move.
Motronic learns behavior and compensates, this will not be overcome by resetting the ecu and as far as I know it dos not throw any codes and the car will run like it has no turbo.If the keyway gives up you kill the engine but i sometimes moves just enough to cause a problem such as yours.
As I said it is a long shot but I know this can happen because when I first got my 3b and changed the cam belt the keyway was hanging on by a thread, and at the time it ran like crap.

It has been determined that its running dangerously (to pistons) lean!! Just tring to find why. Having changed MAF sensor, Lambda sensor, TPS, ECTS and injectors i'm looking towards fuel pump!

You'll be o.k replacing it without remapping.

Also don't forget that this problem STARTED out intermittant and only in the last few weeks has become permenant
