My torque starts at 1300rpm all the way till abt 6300rpm before
it tapers down. Maximum rev is 8000 but limited to 7000.
Its actually not really dangerous unless you dont knwo what you are
doing. BMW has too many checks and sensors in the car so every tune
has to include the fail-safe parameters. So far, with the procede
which requires you to remove wires form the ECU and bypass it, it
is fairly easy to do as each and every wire is stamped with a
number and you take those wires and bypass it. Pretty easy. Been on
this system for a good 4 months now, and i love it. Not 1 problem.
What makes the car fast is not really the engine and the chip but
the transmission that is really quick. Its shift is 0.1s.
Hope this helps.
CHeers!
