New job new need to hypermile

[RDBLHHR]

My name is Jason. I just recently got a promotion to outside parts sales for an international truck dealership. I am currently driving a 2008 Chevy HHR SS. My only mods have been performance. I have a free flowing exhaust and a custom tune. i am creating 300hp to the front wheels out of 2.0L turbocharged 4 cylinder. With my new job I do get mileage but I am all for saving as much money when it comes to the pump. I have experimented with hypermiling before but now I would like to do more. I am hoping to buy another car just for work in a month or so that I will do more mods to aid hypermiling.

Welcome to the site.

What kind of highway mileage are you getting with the car now?

Definitely start by airing up the tires to a higher pressure and start blocking off the front grill. I'd also highly recommend a scangauge or other MPG meter to keep track of how your driving technique effects things to figure out what works best for you and your car.
