I wish mine ran like yours. The engine was dyno'd and reviewed my Xtreme RC and the article shows 39 in/oz of torque which is less than a RB TM323. In the article it actually mentions the lowend response and mentions that once under way it is fine. The only time I've been able to get it to have good power is running it a 290 and I don't want to do that. I'm running a R5 and Rocket Science 30%. I wish mine ran like yours!!! What fuel and plug and temps are you running. I'm calling OS tomorrow about mine.

Some other engine dyno results tested with the same equipment and methodology
