Default HELP! Engine sounds like its under water when I full throttle

HELP! Engine sounds like its under water when I full throttle! I'm not a newb in tuning engine but not an expert either. But this is just making my head ache like crazy! Low end is awesome! but WOT... sond like it's drowning under water. and when gas is half way through the tank, feels like it's leaning out or something....

engine is a .24 Trinity Extech w/ Bigboy Pipe.

ANy help would be appreciated!

Thanks!

I bet your engine is overly lean on the highend. Sounding like it's drowning? I'd check the back pressure from the pipe through to the tank for leaks as the culprit for what you are experiencing.

bad glow plugs can cause all sorts of problems, if the engine started acting up out of the blue, that's my bet

check the simple things first
