| I am curious if the engines r the same between the 175 and 150 optimax. I was told that the only difference is the ecm. If any one knows please chime in. also if that is the case could a person reflash the ecm? thanks |

| A person could, but he'd have to be the right person. Problem is, the right person probably wouldn't do it. |

| not possible also the other difference is the ring on top of the plenum remove that and you will run real lean someone might suggest that thought i would head that off before you really have problems. the difference in speed is minnamal so why bother maybe 2 or 3 mph difference stick with what you have |
