    Well I found one of your videos ..

    Congrats on those high #s and nice tuning but they don't mean shit in 2-3 footers and boat rollers coming at you for all directions my bathtubs got more chop than that video, you be lucky to hit 65 or a MOVING AVG 55 across a busy bay or ocean over 3-4 mile stretch ...

    When your knees are hurting your arms feel like jelly and you feel like any moment your gonna get tossed the last thing your be thinking about is your tune... Believe me

    Bump... I'd like to know what else he has with MaptunerX tune cuz my SCOM has me at 75 MPH on stock prop and "limited" stuff but if MaptunerX will get me 78 MPH I'll do that for 3 MPH hell ya!

    Yellowjacket did you ever get the data from Greenmachine315 if he was running stock pulley and such with the MaptunerX tune? Any details?

    Antonyuk, Nice to speak to you again

    I like your 310 mods. I'm very interested in the catch can and cone mod, stock plate mod you have available. Curious, do you do the porting yourself and have a website and pricing? I believe you can sell a real nice 310 stage 4/5 Kit. I'm wondering what cone you have vs. the one I have from R&D.

    I have MaptunerX for my SXR 1500 but not ready to go beyond SCOM "limited" yet on the 310. I already spend the money on SCOM and at 74.6 MPH 8090 RPMs on SCOM stock prop so not much left to do but shave fractions of MPH on limited upgrades vs weight/HP. One of my final limited mods is having my stock 310 prop modified by David at Impros. I may call it good after that hoping to get to 75.5 MPH. I rode this rocket this morning and man o man it's just crazy fast as is! I forget how quick it is and scares me at 75 MPH on smooth water is still scary cz sometimes a rogue wave or bass fisherman comes out of nowhere so there is tons of responsibility riding a boat this fast IMO. I won't ride fast in rough water anymore after I got tossed at 70 MPH last summer with a week long full side body bruise. I was trying to get a top speed and hit a huge rogue wave... respect

    I honor your opinion and reputation so I would like to ask you what target RPMs should I give Impros when I'm sitting at 74.6 MPH 8020 MAX RPMs winter conditions clean water 91 octane pump premium? My guess would be 8250 RPMs on a 14/18 or stock impeller custom pitched, 94 Octane (just to keep the knock sensor from kicking in) and see what happens - more to come...

    Thanks man!

    I built a 18lb R&D STAGE 3 tune with R@D cams pistons, springs, exhaust, everything I could throw at it.....77.8 mph with 100 octane av gas that he recommends....

    Put the 16 lb kit back on and sold it.....

    Bought a GP1800 spent 1/2 as much running 85mph all day long.....

    Trying to get an 80+mph Ultra is like building a VW Golf GTi and trying to run 9 sec 1/4 miles. Sure it can be done, but why build one if there's other cars that can get you there easier.

    Same with Ultras, they are great offshore racers but if you want smooth water speed get an SVHO Ski.
