Delta between Hybrid Tahoe and Yukon

[OMG its Jason]

I think there must be something wrong with my truck, how is it that everyone gets 18 MPG average on gas models? I'm stuck at 14 MPG combined, this includes 30 min on highway and the rest of the day on the street, shouldn't I be getting more? When I did a long trip to Boston I got 15 MPG average

Maybe you need a tune??
I don't know what you have on your truck, but get an intake/exhaust (my exhaust is not loud at all), then tune it. There is NO QUESTION you will save MPG with a tune. Maybe theres an underlying issue, maybe your plugs need changed? What size rims? I have 24's and I average more than that (19-20 on hwy at 65-70MPH and in the city with no stop and go, I average 22-26MPG at 45-50MPH.
I don't have a tune yet and only have exhaust since my intake hasn't arrived.

Are you calculating the MPG? Or looking at the DIC when you are driving??

It is not always accurate, but then again neither is my math.

It's not bad. Just so long as you are looking at average MPG not instant.

Thats why your numbers are higher.

Hybrid Roof Rack

Just bought a 2008 Tahoe Hybrid.

No roof rack. Anyone installed a roof rack on a hybrid with a sunroof?

Any problems that I should be aware of?

If I order a 2008 Tahoe roof rack from GM, will it fit?

Help would be appreciated.

PM me

nice, the hybrid tahoes look better in my opinion. i think it should you'll prolly have to drill holes tho. the reason there not on there is prolly cuz its more aerodynamic wothout them and they figure since its a hybrid....
