horrible gas mileage? SCT tuner?
Alright well heres the situation. About a month ago i purchased my SCT livewire with innovative tunes, 4" turboback, and a AFE stage 2 intake. I loved the extra power but my gas mileage dropped from about 22mpg highway stock to about 18-19mpg running the tuner. I checked and my fuel and oil filters were just replaced, tranny was serviced, and i had a bad vaccuem hose replaced but to no avail as it hasnt improved at all. Has any body else suffered a decrease in mpg with a tuner or is something just messed up with the truck? Any thoughts to what it might be? Me and Eric have been trying to troubleshoot it but as of yet we havent been able to figure it out. Thanks for any help.
