First off welcome to the forum... glad to have you join us.
Regarding whether to tune or not your trim level (LX) vs. Sport the 1.5 motor is the same. There may be difference in transmission's (CVT, Manual, 10 speed) and depending on what yours is could determine/limit maximum tq/hp. Best bet is to research KTuner and Hondata... see if they have recommended tuners near you and talk to them for suggestions.
