Question for those who run 55lb injectors

[GNVAIR]

I have an Extender chip and a set of 55's in my car. Problem is it is very rich at idle. Blms are 110-112 at idle. I have tried dropping the fuel pressure from 45 to 43lbs with no change. I have also tried the leaner setting for the mass air meter on the Translator box. No change. I am curious if the spray pattern on the 55's changes with higher fuel pressures. Anyone?

Lee,

I have no idea, but just to throw something out there for ya...

Do you have the exteme version? If it has 1/3 higher range and you are on the 4th dip setting for the reg extender, it may interpret the idle gps to be higher and add more fuel?

At least it'll bump this up....

Mike

As long as the BL is pegged at min., your fine.
128s are nice for stockers.
there is no real need to get in a twist with other then 128s if the car is running fine.

I'd worry more about a high BLs then low.

Set the pressure as Bob recommends.
