The dealer also told me that even 400hp is no problem with the stock clutch and transmission, but he advised to opt for a larger intercooler then.It's only a software tune for higher power. I think you guys have lower stock hp cos your gas is low octane. Here we have 95 as lowest octane (euro95) and 98 octane is super+, all available at the gasstation, and for higher performance you can buy octaneboosters to go above 100 octane.
