Tuning our LB7 Duramax using EFI Live & DSP5 Switch! - Truck Build Update EP.8 

In this build series, we restore our tired old 2002 GMC Sierra 2500HD, 6.6L LB7 Duramax Diesel. We replace 90% of the body and add tons of awesome aftermarket parts. When we're finished, you won't be able to recognize this truck! In this episode, we get the truck tuned by Precision Diesel using EFI Live V2 and add a DSP5 Switch. We also undercoat the truck using Fluid Film Black.
Here are the 5 tunes we can select from:
25Hp Lope tune
45Hp Economy tune
75Hp Towing tune
120Hp Street tune
150Hp Racing Tune
