The CIS system on the 930 is set to deliver the same amount of fuel to each injector at a constant continuous rate.

If any one cylinder is restricted in its air flow the ratio of fuel to air becomes RICH, not lean. The cylinders that flow the most do not run lean, but at the correct ratio. This is evident by the poor fuel mileage of these vehicles and the fact that many have gone 100,000 miles before requiring a rebuild.

A lean condition would very quickly destroy any turbocharged vehicle that does not have the engine management capabilities to offset it.
