predator

Bought a predator off a buddy and installed it on the truck. When its idling it seems to run real rough. You can feel it threw the steering wheel. Did not do that when it was stock. The other thing I noticed was when its in high idle it seems to lope a little. Is this normal ? All other programmers I played with don't do this stuff. Not very impressed with it. I have the current updates too.

I have seen a few complaints of idle issue in cold weather, has this cleared up at all since it warmed up (has it warmed up in Indiana?)?

Thanks
