also try and readjust your tip in values. Bigger injectors requires smaller numbers there too.

Here is a link to another discussion:

Here is the formula i gave in that thread:

em injector value:W

Tip in cell value: Y

Hacked injector value: Z

Z X Y

----- = approximate value

W

This is based on the theory that injector scaling and tip in numbers are based on lowering open time.

Example Using crazymike's number on an 04 WRX:

4200 x 151

----------- = 98.45

6442

6442 = oem value

4200 = crazy mike's value for correct idling

151 = oem number for top cell in tip in adjustment

98.45= new value for that cell.

You might wanna add a little bit on top of this just to play it safe. But if the relationaship between open time for constant fuel and tip in the same this formula should get you pretty close to teh ball park.
