Hello guys well many of you may have seen my previous thread about the duramax that I was purchasing and the good news is i went ahead and bought it!!!!

No pics yet because it is at the shop till Monday getting e-brake fixed.

I have some questions for anyone who is willing to help?

Specs:
-2007 LBZ with allison
-standard cab, 8' bed
-4" Rancho suspension lift
-315/75/16 Yokahoma AT's
-4x4 Automatic

The gas mileage on the dash says average is 14.3.

Do you guys think that I need a tuner to recalibrate the speedo and that might improve the gpms? Or do you think the gas mileage decreased this much do to lift and tires? If so will a tuner with economy tune improve mileage?

What tuner do you recommend?

Is the Edge any good?

Any info welcome...

Thanks again for help...

No matter what you need a tuner. Just keep it on a lower setting so nothing gets hurt.

Look up PPE and EFilive tunes.

Yes the tuner will help with mileage.

Thank you..How is the edge programmer?

Yes you need a tuner to recailbrate your speedo or go to the stealership and pay them to do. Edge is good and I suggest getting this one...http://www.meyerperformance.com/pd-edge-cts.cfm
It's a nice programmer with alot of good built in features and you get gauges. I would also suggest getting a TransGo Jr shift kit installed. I would also sign up on http://www.duramaxforum.com/forum/ aand http://www.dieselplace.com/forum/? and just start reading like crazy. There's alot of helpful guys on those 2 forums and the vendors are helpful also.

Is this any good for help with what I want?

I've never used Supechips before but I've read were people actually pick up decent MPG with them. I take it your not looking for anymore horsepower? No you don't have to have the shift kit just for bigger tires but it's a good investment for the transmission.
Here's a link to the shift kit. Look at the first 3 boxes going arcoss and that will explain what the shift kit does. The box is labeled SK Allison-JR. I have one, just have to find the time to get it installed.

I like PPE and Efilive personally. Both got me 18+ but you also have to figure in that with either of those two you can delete the cat, muffler, egr, etc.

Efi live or ppe!
Edge is hard on the Trannys, know from experience lol..
Shift kit, yes! Bc once you feel the power you can get outta the ppe or efi, you'll be I'n it haha.
Efi on an 03 Duramax with 285s 21hwy. Friend of mine has it

Donbt waste your time with Edge, EFI Live with a duramax tuners dsp5 swtich is the only way to go. I have owned both, and would never waste my money on a edge or other programer ever again.
