Well ive noticed that my car is running quite rich, im sure its not a terrible thing but i was wondering if i could get it leaner if it would be more benificial to performance.....how can i get it to run less rich....?

 

well, I would check the O2 sensor. Then check to see if ur injectors r working properly(notstuck open) but with the mods u have it would seem like u would be running lean rather than rich. Well good luck!

 

Dude if your 02 sensor has more than 70k miles on it then go ahead and change it. I did mine just recently and went from about 19.5-20 MPG to about 24-25 MPG (mixed driving and not spinning the tires )
