What RedThree said - I also have it on very good authority that the engine does not in fact run lean either. The pinking/det is due to massive build-up of heat in the combustion chambers as a result of an exhaust that is completely bunged up. Engines run on the dyno (and on the road of course, but dyno cells tend to make it more obvious) in stock form det like bar-stewards and this is a very dangerous condition, as you are all only too aware. The free-flowing exhausts do not experience det in the same way as the fuelling suits that condition much better. I don't believe it's anywhere near perfect and there's much room for improvement, but it's a much SAFER condition for the engine overall. I know for sure which condition I'd prefer.....
.... but there is still room for an ECU re-map and it does seem that the factory are going to offer something on their Stage 2 and 3 kits - note that are NOT offering one for Stage-1 - I wonder why? I hope Garage56 move towards an ECU/remap for their future mods, as that would be the icing on the 'optimised' cake as far as I am concerned.
