finished intercooler piping, built downpipe, connected to stock exhaust for now! haha i have a dump valve we are going to put in later, i want to see how it does with totally stock exhaust
you're using that duramax map right? man I couldnt get mine to work right at all. I saw on your wiki that the pin out is different, tried that and no bueno.
i thought, ok maybe i'll just hit it with 5psi from an airbrush regulator and it went bloop
When I put an almost identical FMIC on my dad's truck, I was pissed because the only way I could route the inlet/outlet piping forced me to put them at the top. I wonder how much difference that really makes in cooling the intake charge.

i havent gotten to confirm if that fixes it or not yet, i just put a efi source 3 bar on it and it was mint LOL
exactly, i am struggling with the tuning on this thing, i can make it work maf or map, and make boost, but i must be missing something, its idling like trash no matter what i do lol

Damn, well at least you admit, something gives you trouble. You always make it all look like cake!
I think you may be seriously underestimating the power you will make. I saw 350 to the wheels on a mustang dyno at only about 6-7lbs of boost with a non-intercooled side mount whipple. The only mods to the 4.8 were long tube headers and 1.85 rocker arms. A pd blower with no IC is almost a worst case scenario for HP per lb of boost. BTW, if you still have idle issues I can probably find a file from an LQ9 DBW with a baby 67mm turbo and an 02+LS6 cam to compare the DBW portion. I know that is night and day from a 4.8 with a real cam, but there might be something about the DBW that is similar.

i have a fairly conservative dyno but we will see
