Now, let's talk E9x M3 trade-in value . . .  |
80-100hp from a "simple tune" will not happen. BMW is starting with a low displacement motor to begin with and is taking much more effort in preventing significant power from aftermarket tuners. Just look at the n55 motor vs the n54. And look at the new M5/M6.
