    So, I have to ask, cause I did not see the HP results on website.
    What is the 4-stroke V6 225 max HP tune?
    What is the 4-stroke V8 300 max HP tune?

    So cool that these are able to be turned up.

    We are still working on upgrading the V6 over 225 and the 300. They have a lot of potential. At the moment we offer upgrades for the 175-200 up to 225 , and the 200-225-250 up to 300HP.

    Did I read this right? You can use a flashing tool to turn a 470lb 4-stroke V6 175hp motor into a 225hp motor? That seems incredible to me. Also, if that is true, does it change the operating rpm range or does it still operate in about the same range?

    Can’t wait to see some results on the 300R. Keep up the good work.

    Yes we can upgrade a 175 3.4L v6 up to 225 HP with the operating range of 5200-6000.

    There are a few different programs for that motor. Send it in with the exact combination of parts and I will see what is going on with it. What coils are on it?

    Thanks Eric, I have been running the motor in the meantime with a ecm you did for me a few years back for a stroker 300X, it runs awesome with that program. It's bad one is on the way. Coils are stock 8m0077471 five wire with the cooling fins.
    Thanks,
    Randy from VA.

    Eric, I heard from one of the girls you received my ECM on the 22nd of Dec., nothing since. Why can't you just install the stroker program? Please let me know something.

    Question on the 175 tune to 225. I have been trying to get a v8 motor but looks like I'll be waiting a long time, so.now I'm considering buying a new 175 v6 based solely on the fact I can upgrade it to 225 or 245 according to the person I spoke with at Simon motorsports. Does anyone have any real world feedback on the 175 v6 tune? If I did go out and purchase a 175 and the tune didn't perform the boat would be underpowered ,
    Just want to be sure before I buy a new motor based on this tunes performance
    Will it perform like a stock v6 225 motor in all aspects?
    Are there any physical differences between the 175 v6 motor and the 225 v6 motor ? Or is it just the tuning
