I had to do all the sump, headers, up pipe, downpipe, bracket, oil & coolant lines. Wasn't easy.
That is the smoothest they could get the lines, he did a few 18psi runs but it looked like a heart monitor going right up & down. Waste gate is halfway between cracked & not cracked, it noticeably fluctuates at higher rpm too. Afaik there isn't any exhaust leaks but they would have picked it up.
I'm also only using a WRX TMIC which I'm pretty sure is holding the flow back a little. I'll eventually wrap the headers & have to make a custom heatsheild for the turbo to keep the hot side hot.
