I've personally have had 3 engines with this tuning and top end all I ever saw was a honest 1 or 2 mph difference running the same size prop before the tune on a Yamaha Sho 250, where I did notice the huge gain was from the 4000 rpm range all the way to around the 5300 rpm, did I Save extra fuel I couldn't really tell you if I did or not but I could notice more in the mid range and it felt more crisp on the top end. 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.
