That's an interesting Q. You can normally use Mykey functions while tuned but, what if a specific function has been disabled like traction control or limiter? Hmm...I'll bet you'd have to go back to stock. It's like my nitrous
tune, which has all the nannies turned off for engine protection. Nothing I can do will switch them back on, other than retuning.
