I join an other graph wich is more significatif except that results (cross) are not at the same rpm for torque and power.
Must point out that TCU tune help in the gear choice particularly whether you are in Sport position and is much better in manual mode.

Thanks for clarifying. Would be strange if Stage 1 tune posts less torque overall than Stock!

But I am now wondering what causes this dip in torque from 2500 to 4000 rpm...

Assume that catalytic converter is the reason. It was the same problem on my GT86. The dip torque disappeared when a new exhaust manifold without cat was in place. May be friends having made mods for Stage2 can confirm.

Yes. The stock down-pipe is very restrictive having 2 catalytic converters and as you can see with my Stage 2 and SPOWER sport cat the torque curve improved greatly!

Here is the updated version with actual TTI dyno results.

Looks great ! This graph actualy reflects what my cars graph looked like, could be because both this graph and my dyno were load based compared the dyno jets. not that it means anything different, gains are gains. I just always wondered why the shape of my graph didn't match the rest of the communities results. I think tony uses a dyno dynamics, and my car was run on a mustang dyno.

That is correct. TTI uses a similar setup to a Mustang dyno, so the results and power curves are different from our Dyno jet graphs.
BTW did you ever get you CEL resolved with the O2 spacer?

I just got my car back from the shop. Looks like I cracked the stock charge pipe

How do you like your RC 200T as compared to your 86? I am an original 86 owner (got the car the first week it was out in 2012) and have just upgraded to the IS300.

I didn't drive the 200T but I'm curious to hear how it feels in comparison as far as power/handling/anything else youd like to add.

Hi,
I also was the first in my area to received the 86 in september 2012, 2 months and half after order passed 2 days after the sale open in France (June 2012) ;-)
Regarding the difference it is difficult to give a formal opinion as it is 2 differents cars. The 86 is a very nice toy,well balanced and funny to drive. It was a manual model consequently the driving is a little bit different and must point out that,some time, I have small regret particularly on little circuitous route. The 200t have more volume and important weight which slow down enthusiam in hairpin bend, with 86 it was his territory and It was a pleasure to drift . I never try with the 200t....... For the rest, 86 was sufficiently comfortable but not comparable with 200t and in any case 200t, even stock, have more power and a very good road holding. I keep a very nice souvenir for the 86 which was a really amazing sport car but it is not comparable to Lexus which remain a must in comfort, silence and driving enjoyment. My wife as well, often talk about the 86 with a touch of nostalgia.

I’m dropping off my car at PPE. They’re going to fabricate a 3” alum pipe from the turbo elbow to the intercooler. I’ll find out if they’re willing to market it.

Good stuff, an upgraded charge pipe is a MUST if you are running higher boost levels. Keep us posted.

I would definitely say that the weight of the car is the biggest difference in feel. I feel much more secure in the Lexus but it definitely is a bit less fun to drive. As expected!
I miss certain things about my 86 but I am very glad to have upgraded to my IS. The 86 was a great car for me for nearly 6 years.
