Yeah, I am really happy with the tune (which was also done on a roller dyno)!

The low-end torque is fierce! Definitely safer to keep the boost down where you have it... and eventually if you get bored with the power you have, you can be sure there's even more fun to be had with it if you want to increase the boost!
So far so good on all the hoses/pipes staying together... haven't heard of it as a problem over here, but I can't say for sure. Hopefully I won't have to find out the hard way!
