    Pause between gears LBZ

    It does take some time to get a quick shift on a 6 speed. In the middle of speeding up timing and everything else I think some guys might get the valves moving too fast in the bore and it starts to mushroom them. The coating and bore plugs only help to an extent. Before I would say its bad...

    Duramax shop near Bham AL

    Rocket city off road about an hour away in huntsville, Al. I have dealt with them and they are very good guys. They have gotten into some serious injection problems on a few 6.7 Fords and got them figured out in a reasonable time. Tell Frankie Justin from Confederate sent you.

    Pause between gears LBZ

    Maybe loverich will chime in but could the fluid not be slippery enough and the valves sticking in the bore? Can you watch commanded shifts and the subsequent successful stroking of the valve in the bore validated by a rapid and consistant change in tfp logic? Sent from my SPH-L300 using Tapatalk

    Anyone own a Volt?

    Pat, When I worked at GM. I did a good bit of training on them. I really enjoyed the way they drive, lots of torque. All the parts are really top quality. They are fairly easy to work on and have tons of new technology. I think you will really be satisfied.

    LML build test

    The 6l90 and 6r140 are remarkable simalar. Our 6.7 ford trans holds up to 650 rwhp. Tuning in our ford we can really jack the line pressure. Start a new thread trans tune or raising line pressure on 6l90e. Maybe we can figure it out Sent from my SPH-L300 using Tapatalk

    Porting to reach high rpm breathing

    I believe this principle is applied when the walls are left rough to create turbulance. the turbulance acts as a bearing to speed the center flow which is 90% of the mass anyway. This was always my argument for leaving the porting of a runner or head rough vs smoothing to a lower ra finish.

    is it normal for "mods" to mess with my signature?

    The mod should have sent moss a message to please remove the link. If what moss is saying is true than I have to agree that it totally reduces the mature quality on dd I have become very comfortable with. I hope this gets resolved Sent from my SPH-L300 using Tapatalk

    Tuning big injectors

    Check all temp sensors A bad reading could change a multiplier table and you won't have the timing advance you need for cold stuff Sent from my SPH-L300 using Tapatalk
