Does anyone have a clue how to basically defeat the wastegate to max out boost on an LLY. I have had numerous Supra's and other turbocharged cars, on these we rerouted some vaccum lines and we were able to see MAX boost ALL THE TIME. Not that this is something that you would want to do everyday, but it sure would be neat to try. I realize that the LLY has an electric wastegate, but I assume that the PCM still controls boost in some fashion. Any IDEAS what to disconnect .etc?

Well...


The LLY does not have a waste gate. It's a VVT, or Variable Vane Turbo and the discharge is controlled by changing the pitch of the vanes inside the turbo.


I think the only way for you to override the control is if you're a computer whiz and can modify the ECM programming...http://www.dieselplace.com/forum/smileys/Geek.gif
