I have Ver6 and I'm runnning rich. I have a walbro pump, and all the other proper sensors. My MAF housing is 80mm and I'm pretty sure that is the stock diameter. I bought a new o2 sensor as well. Any ideas on what else could be making me run rich?

 

When you say your running rich, how rich? all scoobs run quite rich, now if your getting 12mpg id say take it down to a speciallist and have it diagonsed on the machine.

I'm running enough to shoot flames out. Wish I had a specialist to talk to...

 

Has any one actually checked the afr % or are you guessing ??

Mines around 1% - 5% at idle
And 9% wot

 

I don't know what the AFR is. What kind of equipment would I need to find that out. But I do know I'm shooting flames as someone else told me about it..lol

 

if the car still pulls well, and your fuel consumption is not extreme, and there is no black smoke, then don't worry about flames. Do you have a decat pipe?

 

I have zero cats on my exhaust. when running WOT it studders upto speed. Boost sticks at about 15psi(~1Bar) But at half throttle it pulls like a champ. Only thing I can think of is maybe I need to change my plugs. That wouldn't explain the half throttle thing tho.

 

I also have a slightly high idle rpm. It's at about 1000-1300.
