SCT shifting and acceleration - Diesel Forum

tbeall · 07-11-2007, 01:22 AM

I have been using the street tune from Innovative Diesel as a daily driver tune for about a month now. The past week or so, it seems as though my shifting has been a little erratic, upshifting and downshifting a lot. When accelerating slowly it seems to "buck" a lot kind of hesitating. Mileage is down a little, even though I drive consistent.

Has anyone experienced this? The XCal doesn't show any codes, and I don't drive the truck hard. This doesn't occur much in city driving or highway, mostly driving on stop and go byways (which is the majority of my driving) between 35-50 MPH. Any tips/suggestions would be greatly appreciated. I'm going to call ID tomorrow to see what they think.

It sounds like this just started happening, so I doubt it's in the actual programming itself. The first thing I'd do is return to stock and drive around for a while. Let the truck learn again. Next, install the program again and drive it easy for the first 20 miles or so. That should fix you up. If not, let me know and we'll diagnose the issue further.
