Message: [QUOTE="Heavyhaul, post: 532799, member: 761"] My truck has been running great and flawless. All of the bugs have been worked out for over 20,000. Im very satisfied with the tuning I have made and I want to push it a little more. However I believe there is more left in my big charger. Having 4:30 gears presents a problem with loading the turbo. I have made many adjustments to the backpressure, vane control and in the smoke control tables as well as the transmission. I guess my question is how much can we push the backpressure to gate it into the lp turbo? Also how much is to much? This truck has Tow-X turbos gated between the stages. 8 hole injectors but stock flow. Its making up to 41psi and I know others are pushing 50 plus with high powers. Rivets are the new duct tape.
