I just got my UFM upgraded to the "Competition Model" and have run into a small problem. If anyone has any ideas or has experienced this problem themselves please let me know how/if you resolved it....
I have had DD's UFM on my truck for about 4 months now and decided to upgrade it to the "Competition" version. The original model ran fine on all settings. Now for the problem, once I hooked up the upgraded model the truck seems to surge or shudder around 1700 rpm when on level 5, sublevel 5. This does not happen under a hard load, only seems to happen when just driving the truck normally down the road (which is where the rpm's are when going around 50 mph
. Changing to level 4 eliminates the problem. I have not tried a different sublevel yet (I am out on a trip right now, but will check that once home).
I spoke with DD and they said their truck did not do this and they ran theirs on 5X5 all the time. So they didn't really have an answer, they did recommend trying a different sublevel and see if the problem still existed.
I am not bashing DD, they have great service and parts. I am just trying to solve a problem, and I am not sure if it is a problem with my truck or a software glitch in the fueling module. Not being able to run on 5X5 kinda defeats the purpose of the upgrade for me. Any ideas/help is appreciated....
Thanks,
