Potential Tuner
2006 Duramax (GMC) Programming??
I already own a HP Tuner with 4 credit open (I bought it for my 6.0L Denali)..
I've just purchased a 06 Sierra 2500HD Duramax with Allison Trans
Many "packaged" tuners are available for canned upgrades, offering LOADS of horsepower, torque, etc. in tow and street modes.
How long until I can use my tuner on my Duramax and catch back up to my neighbors with Dodge/Ford Diesel Pickups that are running aftermarket tunes with great results??
