You mean the turbo inlet crossover pipe for the R?
As for the Si I don’t think they should waste their time and $$$ on that since they have big turbo kit already that replaces it all.
have used the laptop for years or ktuner lol the app on the laptop won't work unless you have a physical device on the outside. Handheld device like the V2 still needs a laptop to upload tunes and what not onto the handheld V2?
