Do Performance Chips work?
Cold air inductions is good.
I have a stock monte s/c 3.8 and I get 29.5 no cruse, it hurts mpg with cruse on I get 27 ish. I dont care if I drop down to 60 going up hill I just try and keep the supercharger from dumping to much gas into the engine.

He is not boosted and probably in a flat area. like I said get off cruze it hurts mpg. and check your fuel pressure you might need to bump it back up.
