There are better tuners out there for less money.i have a hyper tech on my truck now i have an 03 duramax i was wondering what would happen if i stacked the two of them hypertech/banks 6gun ... how hard is the banks to install? :smoke
I wouldnt adivse going above stage 3 on a stock trans. since banks and hypertech both add timing, it wouldnt be a good thing, stacking is really only for cummins till they get custom tuning for the public, look into a PPE standard or quadzilla stealth 2 or EFIYou would be better off to get rid of the banks and install the PPE Hot Race 2 300HP tuner. I have them in stock.
It is +300HP on level 6
+ 450HP on level 10 (dual fueler required to run on level 10)
