Hey.
I've recently gotten a mail order tune done along with a couple revisions on my 6.0/4l80e swapped 2007 saab 9-7x. I'm having an issue that I'm hoping someone here can help with. If I'm driving in any gear not heavy on the throttle and hold a steady pedal I can see and feel a slight surge in engine rpms. it's no more than 100 to 200rpms but its extremely annoying it is tuned in sd
