I'm also interested in this kind of setup.
How much would it cost to flash a stock (never flashed) ECU ?
Also, how do you switch between the maps ?

They switch automatically when you increase your boost level

Its the "dual stage " flash that does that aspect

The V2 refers to the data logging system I have incorporated to inhance the accurancy of the tuning and also to provide all Dyno Flash customers with the info on how the car is tuned and how it is running

Waite you have a flash that holds Two maps and shifts between them on the Fly? That's amazing.

Typically when the compressor wheel is to big compared to the turbine wheel. David even mentioned that there was partial-throttle surge when some guy was driving one of their cars around. Apparently (from what Al wrote) it is only noticable on spool-up, so I'll leave this to people who know better than I do regarding this turbo. I think the clipped turbine wheel was supposed to alleviate this somewhat.

On the compressor surge - Just about every 20 G modififed subaru turbo I have driven does the same exact thing - its very common on those type of turbos. Not a big deal just something to be aware of if you are considering one of these units.
