I have about 1.5 gallons on my B5 2013 and this engine is really amazing. It has so much snap off the bottom I went up 1 tooth on the clutch bell and it still has great punch off the bottom. I also just switched over to werks fuel and it is equally if not more impressive than this engine. I had a little bit of trouble with high low idle but since switching to werks fuel I set my idle gap and set the needles back to flush and it was very easy to tune. This engine runs really good even when its set up a little rich, I am getting exactly 10 min on a tank running just over 200 degres.
