I got sunburned Saturday at the track.

first day out with the '14 250f was very nice! Susp is already real close to what I like amd the motor is as expected. Over jumped quite a bit of what i usually clear, amd actually crashed once cause of that. Fortunately a bouncer not breaker. Got a ecu tuner and tinkered with it.. got more questions than answers out of that. Anybody have experience with these? Theories involving  race fuel, timing advance, and high compression and high rpm have my head spinning
