310 WHP and 252 WTQ Interceptor X + Greddy Turbo HOLY S@%*
Thought I'd share my results from tonight with my fellow RX8 owners... 
My current setup consists of the Interceptor X EMS, Greddy Turbo, External Tial 46 Wastegate, Unorthodox Pulleys, 3 inch catless midpipe, Fujitsubo exhaust, PWR radiator and Innovative wideband 02 (XD1).
I was previousy running the emanage with my setup with a few of the fixes from the local board gurus like the wastegate signal to the turbo outlet. (Mazdamanaic, Mad Dog..Thanks guys). I had the car tuned last August with decent results but still had tons of driveability issues. Very choppy transition into boost, occasional lean spot in my AFR when going into boost, car would stall sometimes, serious backfire that sounded like gunshots, a funny spot around 4000 rpm that when in boost would cause the car to buck tremendously until 6000rpm and a WEALTH of other problems that made me want to give up this car..and focus on working on my fiancee's WRX instead. Plain and simple engine management was a big issue.
I read great reviews on the Interceptor and decided to give it a shot... I even had Scott fly in frisom Florida to Toronto (CANADA) to come and install the unit and tune the car. All I can say WOW!!!! Every driveability issue I had with the car before is gone. No more backfire, no more stalling, no more choppy transition into boost and a rock solid 11.5-11.8 AFR. The car feels as smooth as N/A but with power I never knew could be there. I'm still in disbelief. I am STILL GRINNING ear to ear after my drive home.
We ended up with 310 WHP and 252 WTQ with a wicked low end pickup. I'm running 275/30/19's in the rear... and the car is sliding everywhere from the torque. Time to go STI hunting..
Check out the dyno ! The first run (red) was with the Interceptor stock base map and no tuning.... and the final run (blue) was after we've finished tuning.

Power still peaks early - around 7k?
Also, just to clarify, the gain from 267 to 310 HP was going from 7psi to 13psi?
The key to making the GReddy kill 300HP is to hold boost longer. So, what does your boost curve look like now? From the power peak, its looks like you're still loosing at least some boost with increasing RPM. What was the boost at the peak power point?

RRRRR, sorry for ranting, but you're an idiot.
EDIT: Oh, and you also probably don't know the real world benefits to having the smaller and "shittier" turbo from greddy.

Wow...nice, I'm still weary of Turbo's long term effect on the Renesis (also since I don't have any turbo experiance) but 300whp is all I'd ever want out of the RX8.
Now...get to a track and report back your times.
