Uneven Throttle - Diesel Forum

This only happens when the truck is cold and its a new thing so it worries me, until the truck gets up to full running temperature when i am accelerating from a stop the rpms go up and down while accelerating you can really feel and hear it especially in the turbo whistle... any ideas?

Never heard of it before,,,,,sounds like a tune glitch though,call sct about it, I bet they can help.

I had a previous post about this. My street tune on my SCT is a little uneven. It didn't seem so bad at first...

It's due to the cold start driving strategy, happens when you drive the truck cold. I'd contact your SCT dealer, they can help you out.

thanks for the help but it happens more with just the edge tuner on rather than the sct... I just use my sct for the track...
