3 weeks and $2000 into my 86 951 resto I've stumbled into a new problem...

After DIY'ing all new suspension parts and new tires, a local German specialist shop did wheel alignment and fixed heater (vacuum line off).

I'm thinking finally I get to have some fun! But wait..now instead of 1.8 bars, I'm only getting a little more than 1. Runs like a n/a!

The shop looked it over, replaced a few "brittle" vacuum lines, but still no boost. I clamped the line to the wastegate, but still no boost.

Anyone else experience sudden boost loss in conjunction with a heater repair?

Any ideas are appreciated.
