New fuel pump = need to adjust map?
So recently I replaced a dead OE stock fuel pump for a DW 325 and it seems the car has a new trick of using more gas. I'd imagine the NB fuel rail/regulator would keep things in check, but my gauge/MPGs beg to differ. Not that I'm too concerned with MPGs, but more worried about the negative aspects of running too rich at idle/cruise.
Have any of you guys gone through this and what changes to the fuel map did you have to make?

Unfortunately, the reason I'm waiting to take it to KO is to get around to replacing the FMS and oil feed line leaks.

I thought cylinder wash only happened if it wasn't sparking. Like a flooded engine, or cranking. I don't think it can happen while the car is actually running. Before you tune replace the plugs. But when it comes down to it I don't see any damage happening if you run a little rich for a bit.

Let me get Richard's car out of my garage and you should come over. FMS, intake manifold removal and re-install properly, and then we'll go dyno at KO. Should only take 1-2 days of fixing and then a day of dyno'ing. Well, 1-2 hours.
