    Noticeable difference.

    The protune tune feels incredible and there is a discernible difference between the OTS Map and the FB Protune! Importantly, the protune got rid of the erratic timing correction in cylinder 6 (it was pulling as much as -8.9 degree of timing before even at part throttle!). The midrange torque and throttle response is certainly increased with the protune over the OTS map

    the real deal

    Posted by Cox on 3rd Feb 2017

    With sport headers vs with headers, ipd plenum, 82mm tb and fabspeed custom tune More power and torque everywhere ... from the bottom to the top end... the car runs more aggressive and pulls hard to the redline... Most noticeable gains : @4130 rpm + 11 kw + 25,5 nm @5400 rpm +14,3 kw + 25,6 nm @6600 rpm +11,7 kw + 16,9 nn The ipd+tb combo helps a bit but the gains seem to be from the Cobb-Fabspeed tune
