No the car will magically know how much fuel it needs, it's running too rich right now because you make it feel self-conscious.

Hint: 99 and 00 injectors are the same.

Going from 265cc to 260cc, gonna say no, but it sounds like you could stand to anyway.

Actually, IIRC, '01 injectors are sized closer to 240cc at 3bar, despite what I've published elsewhere long ago.

But my questions are:

How rich is "very rich?"
When is it "very rich?"
How are you determining this?
Why can't you tune it leaner?

No one's said it yet so I will: ditch the doo doo box or settle for mediocrity

i have a wideband it goes gradually to maximum rich when i hit the throtle all the way to the floor.then it goes back to the middle when im off the throtle.but when i hit the throtle a little bit it goes to maximum rich for seconds which causes my car to stall for little bit!!!! and thats my problem.by the way i have walbro 190
