Hello dannyboy-
I forgot to tell VR that I had a Fsport intake, but really that's just an expensive sound box.
Meisterschaft SS GTS Ultimate exhaust (took forever to get but worth it), GramLight 57Extremes (Winning Blue), H&R sport springs, Cusco rear/front anti-sway bars, Seibon carbon fiber OEM style hood and TS-style front splitter, hardwired x50 radar detector (I wouldn't buy a more expensive one and I'll never have another car without a h/w detector). Besides the intake all done at VR. Good bunch of guys.

It might be expensive for people who bought a used high mileage ISx50 for like $12k.

Mind you all that I'm a novice when it comes to cars but after 6 years of driving this I can definitely 'feel' a difference and the Dyno put to rest that it just may be a placebo effect.
It works. As vividracing mentions I've only got a week on it. Let's just say it doesn't help fuel milage as I've been punching around town constantly. It's more than throttle control, which I looked at years ago, it's as they say 'mapping' a better route than the original timing/restrictions placed on the 2GR-FSE engine. I don't hear that giving up, when it seems it could do more, at the high RPM's as I did. It's just more fun.
I plan on having it at Hot Import Nights Nov. 22nd at Phx Conv. Center. I'm lucky to have vivid in my backyard.

Could I use this on both my IS and my girlfriends?? I don't want to buy 2, and it sounds like one would work on more than one car.

No, it's mapped to only one VIN #, otherwise I would be renting this "unicorn" out.
To answer the Dyno here's VR's response.
'We dyno all our cars in 3rd gear unless it is a new 8speed BMW or Audi. We even dyno our Porsche 991 Turbo in 3rd gear. Doing 4th gear pulls is unecessary and the speeds reached on the dyno are not the safest. The important thing is keeping the variables consistant so the only real variable is the tune showing what the delta is. So re dyno testing is not worth the time on something proven by numbers but more importantly by the customers driving experience.'
FYI: I saw the P 991 Turbo being D'ed and afterwards I felt like I just went into my golf cart.

HMM.... im still a little skeptical because its still not a customize-able tune. Also what kind of changes is this making to the ECU/over the long run of the engine. I guess I will have to see once more people jump on it. and see dyno numbers. My pet peave is watching dyno videos and then having them edit in the screen because you can literally put anything there.
