i bought the u186 & im currently running the 120hp tune.i put in a cold air intake, & changed out the exhaust including the down pipe but am looking for a little more i know i can adjust the rail pressure & timing but not sure how or how much.i also would like to know if there is any way to romove or adjust the rev limiter or not?? does anybody have any input?? or can make a tune to do more without putting it on dyno??
