I would go with Fleece if they're on sale
How much mpg have you lost?Well, I finally got my oil changed (second of 4 free at the dealer)...so I could put the tune put on my Diesel Cruze...AND a chance to drive it on the highway.
Have to say I LOVE the tune. Pulls strong while accelerating and the rolling acceleration from 45mph to 70mph like when passing some idiot blocking traffic driving under the limit who won't pass someone else also driving under the limit when you finally get a chance is awesome.
And as others have said...the tweak for the transmission does wonders as well. Never felt smoother. Feels like a much more refined car now (and it wasn't bad before)...with a lot more under the hood.
Its worth every penny it cost.
So if you are on the fence....you won't regret it. It really IS worth it for more than just the increase in power.
