Tunes for a gasser
Jess, I'm not sure it's that easy with a gas motor. I played a little with my 8.1 and didn't see a hole lot. I think you need to tune it with a wide band o2 setup to get the best results. I'm sure there is a few that can get you a little bit with a e-mail tune. Check with a company called blackbear. They seem to do ok with gasser tunes. Thanks Jeff
