JMG said:I get 1.2 bar (almost 18 psi) on a KO3 (Audi 1.8t Quattro), but I run a Bailey DV, so no ppsssst sound for me....The 1.8t VAG engines are metered so a BOV would give a slightly rich condition during shifts (in theory)
Very true - and I clean my plugs often for it.
However, I have the Tiptronic tranny, so there is no release of boost during shifts. So I only go rich when I let off the gas. Added bonus, no turbo lag between shifts
Any chance you are in So Cal?
