I recommend keeping the cold start revs stock. My manual car stalled several times, this is the only thing that I changed when I retuned.

Haven't logged anything yet, no seeming issues.
Questions:

1/ did you get your burble after turning burble on? Or was it there without turning on the burble? If you specifically turned it on, what were the tuning settings you used for nice-but-not-stupid with M PE?

2/ cold start revs - one of the features I'm interested in (since I have M PE too) is turning off the cold start catalytic light off. But you mentioned "cold start revs". Are these separate features? To my knowledge, the option was simply to disable the timing/waste gate operation that wakes my neighbourhood with M PE on the car and shouldn't change the revs in any way. Just looking for some clarification here - if it just lowers revs, that's of no interest to me. Or are there separate options for revs versus light off?
