Has anyone reached out to tti motorsports usa about their tune? Their site is showing unavailable as well. They created a "hybrid"turbo for the is200t at 1 time and have the tune to go with it. Not sure if they plan on releasing another one or not.

Okay so I've sent in a data log on 2/11 and received a new tune with throttle response adjustments on 2/16. After a few days of driving, it definitely feels more alive and eager to move on re-acceleration. I'll probably be doing another data log to see if any fine tuning can be done.

I have emailed Matt myself to see if he can send me a 1.02 revision. i too did try the learned idle sequence using the OV p5flash utility (reset LV, and reset AT, then, start the car, let it idle for 15 minutes without doing anything no ac) but still no luck, I am still getting code P0505 Idle Air Control System. Has anyone had to replace the vacuum regulator valve for this code recently? I know they go bad, but i do not set a fault with 1.01g-c so i think its just an issue the 1.02 tune file.

I had a P0001 code with my tune, I used a cheap Harbor Freight reader but when I went to a Lexus Specialized shop, the code was actually a P0137 for my downstream O2 sensor. Turned out my sensor had become loose. If you haven't already, I'd get the CEL read by a shop with TechStream to make sure it's the correct code. I had to replace my vacuum regulator but it did not cause any CELs.

How did you read your P0505 code? Have you gone back to stock and is the CEL still there?

had a lot of people ask how the tune performs for our cars, so decided to make a quick video

I see you are running 1.02. Most of the things I have seen so far is that this version has several issues. Have you experienced any of these issues and if so, how were they resolved?
Sent Matt an email Saturday so just waiting to hear back on what he says.
