Fuel Injected motor...miss from 1-3K

[Eric Merryfield]

Thanks for all the replies......I will be pulling data riding around the pits and doing a "fake" staging to simulate the issue....I will try it cold and warm, will also pull a data run with MAP sensor disconnected(did that in the trailer this morning, and it seemed to rev up smoother, not totally smooth, but better than it did with it in....Will be sending off logs to tuner...didn't find any loose sensors, will get a nice smooth low rpm tweak and that should fix the drama.....but staging it bumping it it at idle then on with 1400lb of brake pressure to hold it while it stumbles up through 3 to two step at 4K is a bit of a challenge.....driving it up the trailer is another one!

Thanks

Eric
