HPI Firestorm - tuning
Discussion
yes, will need a retune, if only for the change in temperature between summer and winter (albeit you wouldn't think it today)... I'd suggest you richen the HSN a bit (1/4 turn) and lean it off until it's punchy and you're left with a trail of blue smoke.
Good luck... also best to use after run oil in the motor if you're going to leave it standing for a month or so.
