Since stainless expands significatly more than mild, it can snap the exhaust bolts/studs.
So, it'* safer to use mild for the flange.
That'* what I did with my buddies turbo manis.
I don't like how they used the stock cast flange though. Thats just asking for cracks..

Excuse my stupidity, but what exactly is skewing?
:edit:
Keep in mind this will be for a mildly modified L36, so I think headers are out of the question...

Example .... When you install a front PLOG you tend to have the injectors on the front bank flow 2-3% more than the rear bank.... In your case this can be done through the PCM

The PLOG outflows the ported rear. Most guys see better results with a skew, although ZZP has been on both sides of that fence in the past. Bottom line is that you'll get what you want if you skew. If you don't skew, the opinions are from barely noticable to noticable improvement.

If I had an NA I'd be more inclined to get a PLOG so you might as well give it a shot.
From what I've read you should skew the front injectors to get any noticeable improvement.

What were the conditions you scanned in on both tests? It'* alot cooler now than it was a month ago. When was the last KR scan done, and when was the Plog installed?
