still got some tuning to do....but I feel like Im gaining ground and knowledge of HP tuners. I must say, I think megasquirt and other stand alones are easier to tune. Anyway, here is my latest tune...

I really appreciate your help. I ended up swapping the express van fuel segment into the avalanche OS and it seems to be working. Showing 1/2 tank, and Im pretty sure it was near that before the...

Im looking for a 1998 F-body fuel system segment number. I was told that the express van uses the same one as the 1998. I am using a P59 PCM. I plan on using a 05 Avalanche OS since it has some...

Well the 0411 with flex fuel doesn't support 3 bar map. The operating system I stated for the p59 PCM supports 3 bar map, and flex fuel is enbaled. I just need to know which fuel gauge segment swap...
