Well I just filled up after a full tank plus 1oz of freering.Ended up getting 49mpg with 50/50 city/highway. So that is pretty amazing. I still have the backfire but it is not nearly as often and I cant repeat it like I could before. So I would say that is a good thing. Next, TB sync when the carb tuner comes in. If that doesn't fix it il start taking apart the exhaust.
