Finished the gallon today, still runs really well, the compression is the same as it was after break in, but the power is really starting to come in, I'm running about 1 hour rich of a really good race tune (as I always do with all of my engines), the temps were 240ish, not that it matters, I tune for power not temp. I'm thinking the engine will be fine, I really dont plan on using it anymore untill I need it. My modded engine has 3 gallons on it and it's unbelievably fast and smooth, the compression is about the same on that one, runs and holds a tune really well. I'm going to try and contact RB and see if there is any Q/C issues with the P/S's, but for now I'm not seeing a problem.
