SCT tune and cold start problems

[blacksheep06]

I have the mods in my sig with 93 octane tune from brenspeed and the car wants to go dead during the first minute after startup when cold. I have to rev it pretty hard when I'm backing out of the garage or it will go dead. Actually sounds just like it has racing cams the way it struggles to stay running. Seems to run fine after it warms up.

Do I have a bad tune or what?
Can't be that great if the car is doing that.


Another interesting note is that my TCS button is reversed. It is off when I start the car yet the OFF light is not on. If I press the button it says OFF yet I can barely break the tires loose in 2nd. Yet when there is no OFF light I can roast the tires in 2nd and the car starts fish tailing. I've tried several times, same result.

It was right the opposite before the tune-
chirp 2nd when TCS was on
roast 2nd with TCS OFF.

Yes, call Brent first. It's faster.
I do think the TC button is backwards in the tune. Some tuners do this.
