Well, do I need the special crank pulley with the T6. I don't know exactly how different this ECU is compared to the P8. Some would say totally different, but can it still work with the pectel loom I have for the engine with the std sensors ? Because I would have to pay 800£ for the T6, and few other to make the map, and then maybe another £££ for the loom ? Maybe the first 800£ to modify my P8 would be more interesting on a money point of view.

I do not need TC or diff control, basically the engine is an ex-mountune unit re-mapped by Harvey Gibbs, what it has is als, air injectors, water injection, and that's all I think. So maybe the T6 would be "too much" for my use.

And finally I don't know how much I could get from the P8. As I said it can run ALS, WI, air/air and on the chip it says dizzyless but not mounted on the engine, so may be worth 450£ ?

Lot of questions... :S
