  1. So it's been a while. This is a v7 sti standard crste motor with second hand standard heads off a v7 sti. Supporting fuel system and a link ecu. Fmic and bolt on twin scroll blouch 3.0xt-r turbo. We wanted 400hp with bolt on turbo on pump gas. This is I think the limit of what is achieveable on a bolt on turbo. It is at 26psi to achieve it.

  2. There will be something different with the way the wastegate vac lines are hooked up, worth checking over that before the tune. It should behave very similarly to the TD04 if hooked up correctly.

  3. 14-15psi is about normal for those so wouldn't be worried. If you had the TD04 one set open slightly it would slow it building boost which may have meant you missed the quick boost peak they usually have.

  4. Sweet, that’ll be a 3-port then, almost all of the factory plumbing gets ditched when you do that. Shouldn't be going to the BPV. Should go forwards under the manifold with the turbo inlet pipe to the factory solenoid, and then from there to a port on that inlet pipe. Hard to say why it's boosting differently without seeing how it's plumbed up after that tee. How high is it actually boosting? Could just be a restrictor pill in a line somewhere that isn't right for the new turbo but seems unlikely. Since it all gets ditched I wouldn't worry too much and just try keep boost down and check everything is tight in the mean time

  5. Nah that should be fine short term. Where is that line going? Is transaction from the VF or swapped over from the TD04? Are you installing a 3-port solenoid when you get the tune done?

  6. Probably still a better option than the subtech. Yea the VF45 is twinscroll too. It's basically the same rough design to fit in the same spot, with the same exhaust components as the TD04 just with some minor differences as it is a different brand.

  7. You don't need the air to hit the whole surface for it to work... there will be the same amount of air coming through the scoop. As long as the air is forced to go through the IC and can't go around it... you are good.
