Turbo Uprising
What are you using for boost control, the WG spring and manifold pressure, or is there a MBC installed? If boost coming on too early is causing driveability problems, you might consider adding an EBCS system so you can adjust the WGDC to moderate spool up. Some aftermarket units allow you to load several maps depending on driving conditions.

At PATC they were very knowledgeable about our transmissions and offer excellent customer support. They had no issues with removing and reinstalling the turbo either. Nathan went on the road with me for about 30 minutes to get my driving impressions of the car under all types of conditions. We went from normal driving to the street race roll and then from a a dig. It is performing flawlessly. On the three hour drive home with about 6 or 7 wot bursts it still averaged 24.2 mpg.
More updates coming!
