WI and running rich

[stevieturbo]

If your reservoir is mounted too high, water could be leaking into the inlet tract all the time.

Are you sure there is no adjustment at all on the FPR ?

What about using a piggyback ecu so you can have some control over fuel and timing ?

And whilst this perhaps isnt the best route. You could create an air leak/bypass for the MAF, so it doesnt see the entire volume of air the engine consumes, which would cause it to run leaner.
But you'd need to tread carefully with that
