    Also here is a virtual dyno at 15psi, with and without meth. Stock cam really falls on its face after 5k.


    And where it all started, automatic 7psi virtual dyno from last year.

      So after Kamotors looked over the power curve of my Gt35 and his old one he found that the boost issues experienced were causing a loss of mid range. Intresting part is mine is making a good amount more torque than his old setup.

      Mine is peaking at 18-19psi in 2nd gear, going to bypass the boost controller and see what the problem is.

          Interested to see what the resolution is. I'm running less than half that amount of boost, but I'm having a similar problem.

            Im thinking its either they way I have my boost controller setup, or IronFreak suggested that it may be a bad wastegate spring.

              See if your vac lines are filled with oil or if the MBC itself is filled with oil.
              Worst case is that your welded WG provisional, being at a 90 degree angle, isn't channeling enough gases through it when the WG opens.

              I know Kam's is the same design.. but the less boost you run, the more gasses your wastegate has to worry about bleeding.
              And you're hitting 18psi at full creep, which is what Kam runs as usual.

                Ill check them for oil, I think its the MBC/ they way its routed or a bad wastegate spring.

                The way the external wastegae is setup is kinda between these two where is not at a perfect 90 degree angle.

                  I've run my turbo down to 7psi without creep and its a small turbo that spools easy. So i doubt its a manifold issue

                              Went to drive the car, hadnt been driven in one day( rainy one) and the battery is completely dead. Super annoying, any idea as to what problem this could be?
