Pole Position
It's been mostly rainy here so I haven't driven a lot with the tune. But the few times I have..I can definitely feel the car pull harder. When I floor it, the car climbs the rpm's really smoothly and keeps pushing all the way to 7200 now. Sounds soo good when the exhaust sings past 7k rpm and bounces off the rev limiter 1-2 times before shifting. This one particular street I smash down on my home .. there's a straight part where I go full throttle almost everytime and I get up about 80 before I have to slow down to turn and now with the tune I reach 80 by at least half a second faster now!

We can make the rev limiter whatever you prefer.
Regarding the shift point... there are 2 ways to do it. If you want to hit a rev limiter in manual mode then we can tune it that way, but in auto mode the tranny will not shift at redline. This is no big deal if you do all your hard driving in manual mode. Second way to to is to have it shift at the revised rev limiter automatically without hitting a hard rev limiter in bot auto and manual mode.

Been driving around with the tune for a little over a week now car sure does pull a lot smoother and it just feels so good going to that 7200rpm redline, now just patiently waiting for the Ppe headers to come in so she can really sing.

What if youre already tuned and currently suffer from the torque limiter slip....Would the ECU need to be removed all over again and sent to adjust tranny ECU or already having been tuned is there some other way??

They turned it around the same day they got it - amazing.
I am so glad I put it in. it literally took 5 mins to pull the ECU and the same to pop it back in.
My IS 300 is transformed. Not only is it wildly better above 4200 now (and doesn't die off), which I expected, but it also seems to pull a bit harder climbing to that. The 7200 RPM redline is beauty to my ears. I am enjoying the increased power and I have not even gotten many miles towards redoing the "learning correction factor". This is a fun sedan to drive as a daily driver. I say skip the 350, get a 300, use the price difference on the RR tune and headers/exhaust to a much better effect.

In their last reply they say you need to send the ECU, it seems that tuning the TCU will take long time. Anyway from the dyno trend the car is still producing power until approximately 6900-7000 RPM, you should shift there.
