Ok so i have a evo that isnt boosting however it reads vacuum. i have checked the lines to the wastegate and they are fine, i made sure that the turbo shaft has no freeplay and i have also checked all my intercooler pipes. I have ran out of ideas to check, any suggestions?

Thanks, Jason

 

do a boost leak test, check your wg, if the turbo is good your wg might be stuck open.

 

Isn't boosting on your gauge or no power??
