With ALDA removed, I took it for a short drive and for the first time I was able to get smoke with the peddle to the metal from a standing start. Not black dense smoke but a gray haze. But the boost is still maxed at 9 psi. Is there a way to check if the wastegate is leaking w/o removing the cover or removing the turbo?
