I had a cold weather issue which they promptly dealt with and had me running 100% in a couple hoursI have been having a little trouble with my sft to start when it's cold with remote she doesn't cycle the glow plugs long enough before she starts cranking and it studders and remote doesn't pick up again so sft will have to fix this glitch, funny they know where I live why couldn't they get things right it isn't there first rodeo.
I just got the SFT tune a couple months ago. Just did the full delete so running stage 2. Anyway, I noticed the same thing when it cold starts. It sputters a bit before the rpms finally go up.
