Any difference with the ficm tune on the 58v? Compared to stock how is spool up, you have stock intake manifold no porting and stock manifolds?
I got the FICM tune when I had stock injectors and a stock turbo and I noticed improved throttle response and slightly more low end power. I never ran the truck with the stock FICM tune and 190/100 injectors. However, I did run it with PHP's Hercules FICM tune and didn't really notice anything more than IDP's mild FICM tune was giving me so I went back to it as the EGTs were way more controllable with it as opposed to the Hercules.
I currently have stock manifolds as well with stock up-pipes.
