        • What boost controller? That's what the torque curve should look like....falls off a bit to much at the end but really nice hit.

            This timing curve needs work, if the torque curve is like this because you were knock limited then you need to address that. The boost comes in nicely and stays steady but the torque hit is really soft and the boost target gets hit really soft too. Do you track your car on road courses or Gymkana? Torque comes in nicely for that but kinda lame for the street. It's still rising all the way to the top so you don't have any restrictions holding you back but there is room for much more midrange torque.

                It's an old turbo smart manual. Had a custom 16psi internal wastegate diaphragm made by manufacturer of turbo. It still needs some
                Tuning. The first show hp and afr. Only a little hiccup in the self tuning. My goal was 400 before but ill take the 308 for now tell it blows up

                        Sorry for the super late reply. The turbo is just big and old, coupled with big 270 cams. When I started this project drag racing and roll racing. I did try road racing on a small track with it and had a little fun but the big turbo was no fun. I have add a meth kit since that dyno improved the tq a little.
