Running Rich - How to Fix

I'm running rich, I can smell the unburned gas while idling it's so bad... Should I upgrade my TB to a 58mm? Any other ways to increase the amount of air in my a/f mixture? Should I just get a good tune?

Are you running that hotcam kit on a stock tune??? If so, you will run rich and will need your PCM reprogrammed. I suggest either Madwolf or PCMForless. Both can do a good mailorder hotcam tune for a reasonable cost.

Can PCM4L do a mail order tune on an OBDII?

Yes, but it's a bit more expensive than OBDI programming. Check out www.pcmforless.com for pricing and info.
