Well, made some progress today. First off, cracked the Tial and found a large red (.7bar) and small red (.3bar) spring. The 'wastegate guru' in the shop said that with that combo of springs, the additive boost was going to be all over the place. Per the advice of you guys, we decided to go with the .7 bar spring only, and found the WG to be boost consistently to .7 bar.

Tuning for a while at .7 bar, we achieved 370hp and 340lb/ft at 5800, with rock solid AFRs between 11 and 12.

At the end of the day, we discussed going with an EBC tied in to the TEC system, along the lines of what you recommended Mike. This would definately be very neat, but call me a romantic, but i am a sucker for the old school way of doing stuff. In a nod to the 934's of old, i decided to go with installing a MBC between the seats.

The only decent one that i could find was one like these, but in silver.

Does anyone know where i can find a MBC that looks similar to the factory's?

Anyhoo... Just something sexy about it. Will tune at .9 and 1.1 bars on both street and race gas.

Not bad for the first real day of tuning... but just getting started.
