Oh also - Was using 94 octane/10% ethanol, no nitrous, all boost.
The down pipe we used was the jdm bellmouth, sliced off at the end of the cast piece, and then mated to a perrin DP - the rest of the exhaust is 3".
As for the wastegate - I went with the AVO turbo world 15psi high response adjustable wastegate actuator - Currently pushing 17psi all the way to the redline.
Here's the pics of each -
