com'on man,our cars have knock sensors and with each log tuner attains, also tells how much knock the engine has,so he adjusts timing and fuel accordingly.its so simple.and by Butt tune i think you mean street tune not a dyno,than yes street tune is supirior than dyno tune which we just did for your kind info.
i think you people think that the car was standing idle when he tuned it. we were on ring road for 2-3 hrs taking 3rd gear runs and logs while he tuned it.Dont you see the Dyno graph? its so smooth and torque curve is so flat through out the RPM range indication a very nice tune. Why you say its underpower tune? an engine with OEM 220 hp(190 whp) generating near 252 hp(222 WHP) is an underpower tune?
Plz know what you talk.Dont label some accusations on some heard things.
and graph down is WHP not BHP.
