Yesterday; pulled down the ke55, found out that it has a 3k head on a 4k block.. was consuming a lot of water too.
Today; finally finished off my ebc installation, holy crap I've been missing out! Massive improvement in boost ramp/response and still the same power/boost setting I will have to spend the next few days tuning it a bit more. Cannot recommend enough if you think your wastegate is opening too early!
