Hey I just bought a 2007 Chevrolet 1500 4x4 with the 6.0 Vortec Max in it and the gas mileage sucks! What do I need to do to get better fuel economy? I am going to put Granatelli wires on it this weekend that I am robbing off of my jeep. What about a PCM tune? Who is the best? Thanks for any help!

Oh and I do pull a 6500 bumper pull camper about once every other month - so I don't want to ruin my towing.

I got rid of touque management and it helped my truck out alot. You can also have a tuner scale the TQ management back also if you wanted to keep it. Where are you located?

What kind of mileage are you getting?

id imagine intake/exhaust would do you a lot more good than new wires..

When i think gas mileage mods, those and a tune are at the top of the list

I have a 08 VMAX ECSB 4x4 with 3.73s and factory 20s. It has a Corsa Touring catback, Blackbear tune, and is lowered 2/3. I am currently getting 16-17 in normal driving and 19-20+ on the highway.

I am currently getting 12 and 15. ECSB? Extended cab short wheelbase? I am looking for someone who is well known and does a good job tuning - how do I get in touch with Blackbear and what does it cost? Sorry for all of the ??? but I am pretty new to this stuff.

ECSB is extended cab short bed. There used to be 3 bed lengths: short, standard, and long. If you look at the GMT900 forum in Performance Trucks (tab the the top of this page) there is all kinds of good info about our trucks.
