I've been running this tune since November with no issues. It is nice and conservative. No weird idle or anything like that and feels good at WOT. We are still working on getting rid of the issues specific to the fixed pulley. I should have v3.0 coming soon with a bonus race fuel map.

Bonus: This tuner also drives an E55.
