A CAI will help some,Next will be a Catback Exhaust,if you have not done that yet.And between both you should see some improvement.

you see my list, and i was only getting 15 until i put a diablo programmer, and with a little help from a member on here, i fine tuned it, adjusted everything i could on there, and now am starting to see improvements. i havent had time to check more than one tanks worth, but i saw a 1 mile increase so far.
