The Nizpro has two tunes one that changes the factory 6300 rpm Rev limit to 7000 Rpms or the second tune which Maintians the 6300rpm limit. The big misconception about tuning using the Nizpro he was asking about is everyone thinks it's gonna just make your boat gain 5 or 6 mph and that not the case unless you are tuning a stock 200 4.2 liter sho, the 200s through the 250s are physically the same hardware and the power is different from the tune maps installed by Yamaha. That's true, I posted the video on page on just for grins, the tuning is what the original poster was asking about was the gains and how effective it would for his situation at a price point. So does anyone have any real world experience with retuning the SHOs.with the Nizpro Marine tuning program? The $1500 doesn't bother us - its the worry of possibly damaging the 250SHO, and losing all that trade or resale value to offset the new engine cost.

We are out of warranty, and we can spend $1500 to retune the SHO to 330HP, or look at $30k plus to repower to a 350hp engine, likely a Suzuki trp.

So we ran across the Nizpro retune kit, which reprograms the ECU to run higher RPMs and changes the HP band up to 330HP - supposed to improve low end torque, mid-range power and overall fuel economy, which is really what we are after. Now, I know the X3 is not a speed hull, but the fuel burn is terrible trying to operate at these higher RPM levels to maintain a decent speed. It will run all the way up to 56-5700 as currently propped, but max speed is around 43-44 mph. The rub - we are constantly running it at 49-5200 rpms and turning about 38-41 mph, depending on conditions, and around 43-4600 rpms to run 32-36mph. So, yes, it is underpowered for a boat as big as the X3, but it runs perfectly, has solid hole shot and overall we're happy with it. So here's the deal - my fishing partners and I just purchased a 2014 Shallow Sport X3 that is rigged with a 2014 Yamaha 250SHO. Any ways I do love the results of the tune. The reason I decided to check around here in Denver Colorado to get it flashed and tuned instead of getting the Gurued gear one was because that ecu is tuned at sea level and I asked around about that and was told it would be better to have it tuned here locally in these conditions 5280 ft above sea level.

They also said they have the Flash Tune license # for my bike on file and I can bring back in to have it tuned again without having to pay that $ 150.00 again. This thing Rippps!! They charged me $424.00 for the work and $150.00 of that was to Flash Tune to get into the computer. I don't know what these numbers would be at sea level ' I'm sure higher ' but I can say it is a completely different bike now. This sucks because I can't find my dyno sheet results but I do remember that the first numbers were 168 hp and after they were done it was 182 hp and the torque went way up also.

When I brought the bike to them after having Akropovik cat delete and pipes, plus the power commander 5 put on it from another dealership that didn't have a dyno, it seemed to me to be running rich, it was sluggish out the gate and not that responsive.

They said that this software does all the same stuff. I had them look at Gurued gear website and see what all they do when they reflash theirs. They did say I didn't need the power commander but since it was already there we left it and used it also. They also kept the power commander on it and used it to do the air fuel adjustments. I live here in Colorado, Vickery Motorsports is the dealer who did the ecu flashing, the flashing software they used was Flash Tune.
