I'm a proud owner of a B5 1.8T A4. It is manual and possess a sort of retrograde s-line trim sport package with quattro. It has 156,000 + miles but is well taken care of and runs like a dream. I was wondering if anyone had any insight on a variable boost control addition? I'm days away from upgrading my ECU to an apr tuned calibration and was curios about adding a VBC mechanism, especially since they are not incredibly expensive. Differences between electronic and manual vbc's and can my car handle it at this stage?

 

You don't need any of this stuff.
