Getting down on throttle sounds like plastic popping in tank

alrighty sharky's
been a minute , got out today to rip up some asphalt and every time i would get down on throttle on my 12 FLTRX, sounded like popping plastic crackling from tank or something.......now if i just smoothly accelerated without putting the hammer down did not notice it ......any input greatly appreciated , wondering if anyone else experienced this and had the cure

That was my first guess. It was alarming when I first bought mine... it was more prominent when the engine was hot. My explanation was that it sounded like bb's bouncing around inside the gas tank. Used an octane booster and it didn't fully go away, but was a lot better.

What you've described sounds like spark knock or pinging. Either try to drain out the gas or run that gas til you can fill it with better gas and see how it goes. Also check to make sure your tuner is working properly

Non corn gas don't have the octane in it we need. You need a good octane booster if you plan on using non corn gas.
Get some numbers together and bring the octane up to above 92 and you'll be fine, or just use 92 octane corn gas.
