I found this looking around for mods...does anyone have either of these installed or just have any knowledge of what exactly these do and gains that could be expected? I appreciate any knowledgable input

425,000 yen, haha are they nuts?

 

http://www.impul.co.jp/ -sorry it connected my hyphen to the link last time

and also, can anyone explain what the "trade-in" price is for, what would I be trading in to them?

4000$ for throttle lol
