I've been slowly testing the different tunes. When freshly installed my Map 2 clipped the boost safety setting and reverted back to Map 0. I emailed Terry and he said everything looked fine and could increase boost safety slightly. Zero problems since running Map 3 on 93 octane and will move to E30 soon.
You're doing it the right way, amigo. Every truck is different so it's all about what works for you and your truck.
