I'm looking more and more at his dyno graph and coming to a conclusion that something is up with the dyno. The boost starts dropping off a bit earlier than usual and the same is noticed with the AFR change over that we all see on other dyno's with the same tune. I think the dyno is graphing about 200-250RPM behind and that could cause the HP equation to incorrectly display the output. Not sure on this but would like to see Nuke's car on a Dynojet.

maybe that dyno wasn't accurate. good for showing before and after mod differential results but not for actual final numbers?

The dyno is probably worn out and loose from all the supercar testing in Dubai. j/k!

BTW any 16 owners notice if they can in stock tune not reach 15-16PSI unless in sport? My 17 only gets 14PSI max in normal driving mode but 16 PSI in sport. Now if I put the car in dyno mode its a whole different animal.

Yeah bro not questioning your integrity or anything with that post just throwing out possibility that it's not the most accurate representation. I have no doubt that your car feels really good right now.

Nuke, what's the octane rating on the fuel you get? And assume it's 'pure' as in no ethanol?

Hold the "trac off" button down for like 5 seconds. It shuts off: TRAC, VSC, PCS and a few other "safety" features. Basically makes it a real car.
Just pressing the "trac off" only disables TRAC partially. There is another way to do it at startup with the brake and emergency brake but I forgot the sequence now. (Used to do this when I would drag race my 2011 IS350)

I've never seen a difference in boost reading when in SPORT/ TRAC off mode (Dyno mode). We do get to bounce off the rev limiter in manual mode and i found out on my last dyno session that if in automatic the car won't shift for itself. I guess it needs to register front wheel motion or something.

I talking about I only get 14PSI in normal mode but if I switch to SPORT I will get 16PSI. At least that is what my boost gauge on the dash is showing me. I have not tried it in 'dyno mode" and normal. Every time I do it I'm playing around in SPORT. I will try it in NORMAL on the way home from work today.

BTW: Your 200t looks like it would have beaten my 2GIS350.

The 2nd Gen IS350's are quick. I am definitely making more power out the hole, but that V6 would catch up. That's why we need that limitation issue fixed, i'll be happy knowing that i can beat them.
