I've been working on a good performance with mpg pickup for my brothers LBZ CCSB 4x4 truck. So far, he ran stock a 7.89 0-60 and 15.8 1/4 G-tech. Later that night, with a tune similiar to this, he ran a 0-60 7.4 and 15.2 1/4. Now, I tweaked it a little bit more...added a little more fuel and messed with the vanes a little bit. Can someone check this to make sure I'm not going to blow anything up on the LBZ first and any advice you could give to give him a little more performance and mpg. Thanks!
