My LOUD cammed & FBO e55 SCREAMS with the redline raised & new TCU tune! straight piped & murdered!! HD

Trying out the new MK ultra tcu tune. Raised the redline for the cams and having fun with the new A and full M mode. As you can see at the end of the video it really wont let you shift unless you tell it too! I highly recommend this TCU tune! screams even louder now when paired with the straight pipes.
