Hi so I have a stock VT 2015 and recently added a short ram cold air injen intake and it seems to use more gas using it then the stock intake. im using already
1. Full synthetic mobil oil
2. 91 Mobil gas (premium)
3.Tire pressure checked regularly
What am I doing wrong ?

New intake means heavier foot. Be cognizant of it.

What is the mileage that you are getting? Maybe others are getting worse?

Two things you're doing wrong:
1. Premium gas - your VT is designed to run on 87 regular. Running premium is not gaining you anything on a stock tune. You're wasting money.
2. Your right foot - like RPW said, the intake makes sweet noises and it causes you to be heavy with the right foot.

Mine's getting on average 24.5 MPG and I drive mine hard (full bolt-on w/ tune). What's your MPG?

While the manual does state this, these engines are notorious for throwing rods through the block because of LSPI (low speed pre-ignition). Using high octane gasoline helps mitigate this phenomenon.

Yeah I was going to say it’s been proven to be helped on the turbo forum.

26 MPG is actually really good. In my opinion, these engines benefit greatly from removing the cats, which is the most restrictive point in the exhaust. Even a high-flow cat will do wonders.
