id just keep your p28 that i gave you...it ran right and whatever you were using the other day was killing it making it run too lean with will detonate your motor over time....remember to measure your fuel mileage i believe you should be getting around 250 to 300 miles out of a tank...also remember h22s are hondas big blocks...you arent gonna get the gas mileage like you would outta a d or b series...but even with that said my b16 with a walbro 255lph fuel pump and ls injectors im only getting 30mpgs so be fortunate of what you got...i know its expensive but i run premium in all my vehicles so i feel your pain lol
