I'm sorry to hear you are getting such low power numbers, especially considering the large amount of nitro (20-30%!!!) from an engine that weighs over 2 lbs. .

Maybe you should step up to a BME55 and swing a 4" larger prop at the same rpm, on gas. Or, perhaps, add a tuned canister muffler and add another inch of propellor at the same rpm??? or add a 3-bladed prop on top of the canister muffler and be quieter than any pattern plane out there with almost double the thrust???

It would seem that you are disappointed. Perhaps a change to gas is in your future.
