Toyota Tacoma 2gr-fks sound level after OTT Tune.

A quick observation of the sound levels on my Toyota Tacomas 2grfks after receiving the Ott tune. I'm not exactly sure why, but the engine is noticeably quieter with the OTT tune. is likely to do with the demand of which injectors to use and at what time. and obviously, it's possible the other parameters, such as the cam profiles ignition timing and overall fuel mapping. nevertheless, it quieted down the normal ticking/nocking noises that the 2gr-fks, which is completely normal.
