Any change in the engine's setup, that causes it to be be more 'volumetrically efficient' (as in cramming more fresh mixture into the combustion chamber); will cause it to act 'like a dog'; as if too much nitro is used.
May I ask a question?
I'm going to assume that the higher the RPM the more 'volumetrically efficient' the motor will be, with a tuned pipe? So that said could a engine run "ok" on the ground at say "X" RPM <in my case 14,5K> and "Y" Nitro <again in my case 15%>. However once in the air, and possibly unloading over the 14.5K it now "acts like a dog" as it's being .... how should I say it to make sense.. over boosted/supercharged at it's newer/higher unloaded RPM range?
