A/F running rich

my 03 svt is running rich and bogging itself down aswell as blowing excess fuel out the exhaust, at idle my a/f gauge is reading 10.0 which is rich, no codes and ive pulled the battery and reinstalled diablo sport tuner (have mafia hooked up too), only thing I did was tinker with the mechanical boost controller which I didn't even get to drive it to find out. any advice or help would be great thanks, car is turbo'ed with bigger injectors if that helps

Make sure you didn't knock off a vac line when you were messing with the BC

it has been running fine, I was thinking maybe I reset the mafia mass air some how, and there isn't any custom tune on the diablo just the standard performance on. The maf is after the intercooler, haven't looked at the maf just yet to see if its dirty

So you do NOT have a turbo custom tune on your SVT

I would not drive that car with out one or you will be doing an engine , what size Injectors do you have , you do NOT need the MAFia even on the car if you dont have a custom turbo tune

Hey tom I know we just spoke on the phone but I came across a local tuner guy who said he could help, also I remember you saying something on another thread about tuning the predator with having a passenger in the car to watch the a/f mixture, could I get a drivable tune going that route without having to data log it?
