Well I have had the truck for last 100000 km been awesome truck. But I'm getting board of it and want it a bit faster. It's my every day truck I use for work pull traler often. looking to getting a car houler camper and want to be able to pull it around efficiently could use power there. I also sled almost every weekend. Drive 8 hours each way with a few sleds. So if there's anyway to get more fuel economy I'm in. The truck currently has 4" straight pipe, air intake , efi tuning, and stock transmission that slips a little with hard shifts at time.
