I have a small handful of customers that have had similar complaints that the rollback didn't offer any significant change. In many case, the problem was related to a sensor problem (the EBP sensor specifically) and once that was corrected the vehicles performed much better and economy improved. I still have 1 or 2 trucks that just never saw any gains and I am at a loss to offer an explanation in those situations.

If you haven't already, check out the EBP sensor and see if it, or the exhaust tube to it, are clogged. Clearing out the sensor and tube just might help.

Let me know what you find.

Tim,

Those are awesome numbers! I'd say they are probably above average, but certainly not going to complain.
