magnason tuning issues

Having some cold start issues on a 05 sut with maganson radix kit. Has anyone out there had any issues with cold engine drivability?
Thanks for the help

Try reflashing the stock pcm tune and see if that makes a difference (don't drive it though!!). That will tell you if it is the tune or something else. Any ses codes?

Call Allen at Nelsonperformance and have him make you a real tune :D

I have found that magnusun actually makes a pretty damn good tune for their setup, while Allen's tune is far better on the shifting side and for getting rid of tcm.
