No not the banks at all. Doing the MP8, and from what I understand it's plug and play. They set it where it will not hurt the motor or trans but one could add a piro and go even higher with temp monitoring. The trans is supposed to take up to 1250, same trans as the ISL 400 uses.
If I have a high(for us) milage year it could pay for itself in 1 year if normal year 2 years plus have the xtra power I need for towing the 8500# trailer and towed. Never have been what I would say short on power but I do like passing the 18 wheelers on the hills,smile,big smile!
