All tuned! Nice improvement in the mid range, no more CEL, and best of all speed delimiter! Now just waiting on the supercharger! 
BTW those of you that didn't have the TSB fuel voltage adjustment done, this tune includes it also!

Actually I just scheduled a dyno session next month to see the difference in the tune, I might do a max speed limit test there, safe and controlled.

Lol... Most likely, just have to find a long stretch of road in Mexico, or once I get the supercharger. Actually I just scheduled a dyno session next month to see the difference in the tune, I might do a max speed limit test there, safe and controlled.
Not much really, he's from Canada, well 95% of them were Canadians lol. Just straight pipes from the stock headers, that Rocket Bunny Kit is dangerous BTW, well maybe the rear wing causes it, but anything past 125 MPH, it get's real squirrelly. The interior carbon trim is silver, which was weird to me. I'll consolidate a bunch of videos of him and I going at it in one and put it up.

Definitely noticeable! 
Thank you sir! The video is below for the before and after the tune is below, I see a .2 sec difference from 104-130 MPH. Let me know if you see anything different. Otherwise, more data will come next month from a Dyno!

Howzit brother! AWESOME thread and build!!! Freakin SICK man! Question on your ECU tune: who reflashed your ECU? Did you have to send your ECU to them? How do you like it on the street? Can you feel the difference?

The Apexi throttle controller changes the throttle position of the RCF, the tune doesn't change the throttle position, the tune improves ignition and fuel maps to make the car run less rich and make more power. The TSB is not a anti-lag, but it fixes a problem with the fuel pump regulator voltage, before the TSB, some of the RCFs had problems with the fuel pump regulator where if you stop at a light, the fuel pump regulator voltage would get so low that it would cause the fuel pump to make noise.
