Default Set-Up Thread

I did a search but didn't find anything like this around. What is everybody running for stuff, and what are you getting out of it?

What turbo do you have?

What, if any, intercooler are you using?

What is your maximum boost?

When do you start building boost?

When do you reach full boost?

How much horsepower do you make?

What kind of ECU are you using?

What is one thing you'd do differently next time?

I know there are a lot more things that could be asked, and they would all make a big difference in the overall performace, but this seems like a general overview of a set-up. If you have something in your set-up that makes it better or worse than a similar set-up on another car, what is it?

lmfao, funny man...

to OP-
your exhaust has also a lot to do with spool ad power, try to go with a 3" right of the turbo for best results, make sure that you get a mandrel bent exhaust though, crush bent s too restrictive.
