Efi and Edge Juice with attitude

[Ne-max]

Got a question for you guys. My buddy has a 03 duramax and is running a edge juice with attitude. Recently he lifted it and put on 35 inch tires. He wants me to correct his speedometer since its way off. The question is can I use efi to correct sice its a edge juice thats not in the computer? Any pointers on what I all need to change other then tire size?

Depending on the tuner and setup you have, should be able to just email your tuner and get the change.

Should just change tire size and maybe speed limiter options. If your going to use the license, why not just get a dsp5 setup?

Also could just be my shitty luck but my edge w/ att never corrected my speedo 100%. Recalibrated several times but stayed about 4mph off. Just trying to help from wasting time. Good luck bud!

No reason to go with Efi cause he's happy with the tunes he has. Yes it will cost 125 for a vin unlock but still cheaper then paying someone.

Ok I got the tire size changing part figured out on the efi part. Now can I change that and he still can run the edge?

:thumb:You'll be fine it wont hurt anything to remove the speed limiter and adjust the speedo hell you could adjust some other stuff if you wanted just for better fueling

I have to play with the tire settings. If I go off EFI's calculator, it is almost always off a mile or 2. I would unhook the edge while pulling and flashing his tune too

Thanks alot man. Hes really happy with the edge so I dont see any need to change anything else. Plus lifted on a stock allison already scares me.
