Around town which is 90% of our driving the MPG increase was about 5% but the cost is around 30% more. HWY was about 9% better MPG. And no noticeable performance changes.

I do have a CAI on it but not the CAI tune.

Thanks for the reply.
Perhaps it's not really worth it for you to put out the extra expense. 5% does not sound like that much of a benefit. The ONLY double digit increase is in the expense.!

Maybe once we can tune and add some forced air I'll run premium.
