Yeah, I asked about this a couple of weeks ago... no response.

I don't like this turbo.  We dyno tested that exact turbo a couple of weeks 
ago (same place you dynoed your car).  It was RS2 EM/injectors/MAF and the 
"popular" RS2 software with the VMAP.  It made 337hp peak, but hits no sooner than 
4k rpm, and has a 20ft/lb torque disadvantage to the RS2.  I have the dyno 
chart if you want it... and it has my RS2 results overlaid on the same graph.

However, if you want one of those turbos, mine's for sale.  It probably has 3 
or 4 hours on it.  In all likelihood, it would be a really good turbo if we 
didn't live at this altitude.

We will be testing a different Garrett hybrid next week.  Driving impressions 
are great. Hits earlier than RS2, and makes strong top end power.  I'll post 
the dyno results to the list after we test it.
Take care,
