inTgr8r not only price but as some of these guys above mentioned, TTFS is big talk in M3 forums, or specifically the S54. I've read/heard that TTFS squeezes out the most HP possible, and well the price isn't too bad, however, I do agree with you on your statement on engine management.
That's good to hear dbarton62!
