How is it increasing performance? You need to post up what parameters in your ECU it is changing to get extra performance. Usually those chips are just fooling a certain sensor or group of sensors and the response is short lived as the ECU relearns. I'd be calling RV6 or another legitimate Honda tuning company if I wanted to tune the Pilot.
on the 2015 There are two ECU' controllers 1 is for the engine and 2 is for the transmission ... if you have the correct Honda Legitimate tuner you and delete the VCM for an example .. Without the hardware engine mods the tune is only the icing on the cake . Find a real Company that does the Honda car tunes ..they should know what to recommend for you.
