Just recently installed long tubes off road x pipe 70mm mass air for 19#ers 65m throttle body and cold air kit probelm is now the car is running really rich there is no ses light or anything just running rich so I was wodering if a bump the timing up some will this help or hurt the motor oh yeah the timing is already at 14 degrees so if I bump it up I'll be going higher from that.

thanks

It would be better to buy a pressure regulator.

Do you think it's running rich because you can smell it? An O/R pipe will do that...............

Some say that LT's can move the O2's far enough away to cause issues, but I havent seen it personally.

Good luck.

cats burn the unburnt fuel in the exhaust system. no cats = unburnt fuel coming from tailpipe. its not an unusual situation in your case
