I have recently installed the innovate motorworks flex fuel kit and gauge into my 2019 accord sport 2.0t. I have a ktuner v2 and i have a stage 2 tune with flex fuel enabled. I was wondering if anybody else has gone beyond this and further pushed boost pressures beyond what stage 2 ktuner has on ethanol, and if so, where could i start to do this to my vehicle, i am not experienced with custom tuning on ethanol because this is my first vehicle that has allowed me to do so. Any help would be appreciated, possible values used by others, or good resources to teach myself how to increase boost pressures or further tune my vehicle in any other way, i do not have the money to pay for an ethanol etune which goes for around $700. Any help is greatly appreciated! Thank You!
