The farther the intensifier piston is able to stroke, the more HPO that is used. When you get into really high pulse width, the piston goes a long way.....and when it happens very often (high RPM), then you begin to tax the pump.Seems like as small as stock injectors are, that stock oil should be able to keep up. Is it just in the tuning?
Obviously, the SES light can be disabled for this code. However, it's not recommended because it's masking the problem. There is a lot of performance and efficient fuel usage on the table when the ICP suffers.
