And what cars can hit depends hugely on how conservatively/aggresively a manufacturer rates his engine.
Take my new street car, a direct injection 2L Turbo GTI; VW rates it at 200hp; most people say it makes over that from the showroom (210??). And Andy, can you definetively explain to me how you can judge the net results of whatever ECM tuning is being done as its applied to your magic formula?? Sorry to call a spade a spade, but it seems like bullcrap to me! If some cars can't hit the numbers, I don't think you can blame yhe ECM. phil
