The real difference between me and the rest of you guys is I'm a few years older and I've been at this a few years longer. Most of the people who reach my level find jobs in the industry somewhere, and covet what they know as "trade secrets." I freaking love cars too much to do that, it is now and always will remain my hobby and my passion.

If you have 3500-4000 rpm powerband at full boost in your Honduh, with no big dips in power at the lower end of that range, your car ------- rules, end of story.
I learned this a long time ago. All this full-rice HT ---- where you run a GT42 and make 800WHP, but at the expense of boost response and throwing the first 1/8th mile out the window. Wow you made 800, but the car only runs low 10's, WTF.
Also they always tune on dyna-packs, which erroneously load up the engine and give a torque curve that is in no way related to actual running conditions.

The problem is that most of these giant turbos get you to peak efficiency at peak rpm. That's not ideal. You want the powerband to sit accross the center efficiency islands.
I wish I could spend money on a smaller turbo for my D, which I might in the future since this SC60 (60-1 basically) will go to my GSR build. ONe day, one day........
