hi, i just put a new engine in my focus st. i used my old turbo and the car is running great. but one issue is the car is only hitting about 11 pounds of boost. i’ve tried multiple tunes and it did nothing. if anyone has an idea why this is happening i would appreciate your opinion.

You may have a boost leak. I had a similar issue where I was only hitting 15psi while getting tuned. If it is a boost leak, this link should help get you started.

you may be right. u lifted the car yesterday and made sure every hose was tight and secured and even checked to see if there was any damage to them but everything seemed good. maybe i’ll rig up a tester to be 100%
