Hey everyone, got a little bit of an oddball I need some more help understanding. Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak).

I emailed DP about it to see if there was a way to help it out tuning-wise. Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.

Thanks in advance!

 

It's the tuning. One map specifically.

 

Appreciate the confirmation Cleatus! If I don't get a definitive answer from Jody on if he has an update to fix it, I'll look to see if I can find someone else that does 256k tuning that can help out (If I trusted myself not to blow the truck up, I'd try and cure it myself - gonna leave that to the professionals for now).

This may give me the perfect time to switch to the Hydra, though. Then I'd at least have access to more tuners/possibilities.
