HP increase module? Deere 3038e

I always thought the yellow gear thingy was the 540 PTO indicator. Always learning something at TBN

Ok...I stand corrected. Optimal cutting is 540 rpm which is 2500 engine rpm (roughly). I was trying to make an example...my mistake.
If I have light duty cutting IMHO a bit lower tractor and PTO rpm is okay. Otherwise why even have a throttle. Everything should simply have a solenoid switch. Start tractor, flip switch and it's at 2,500 rpm.
My point is the module increases power. Fuel usage remains to be seen.
It's not for everyone and everyone does things differently...right or wrong.

I don’t understand when people talk about it running leaner? It’s a diesel, they vary the amount of fuel injected to make more or less power. The only other way would be to vary the injection timing and I’m not sure there is a lot to gain for power there.

Coming from a Dodge with a Cummins that had a chip on it they increased boost and fuel at lower rpm’s. This was pretty much well known on how they were getting more power. In the case of the op and his chip we don’t really know what it’s doing but educated guesses can be made. If he has EGR it could be turning that off I suppose but the way tge chip makers have been fined I doubt it.

Wasn't trying to be nitpicky, sorry if it came across that way. In your simplified calculation for pto speed I think you may have neglected the effects of ground speed and terrain. When doing light mowing on basically flat ground (5MPH and 1600 engine rpm) a bushhog wouldn't notice the difference. Same settings going uphill and the engine starts to bog. Heavy grass starts to bog. The engine/gs/pto combination doesn't provide enough torque to do the job.

A person may think that they are being easier on the engine by running at a slow speed but, once there is a load on it to bog, the governor has whacked the injector wide open and the turbo is creating tremendous heat. At low rpm, it doesn't have the water pump speed, fan speed, cooling intake air for the turbo, etc to operate under those conditions.

I agree, there is always a sweet spot for rpm’s where it’s not spinning too fast or too slow.

I'm trying to explain from my recliner, I'm not at the tractor or paper manual in hand...so I called them. 812-618-9166
The tech said at end of the fuel rail is a pressure sensor. I unplugged it and module leads now go between the two. What it does is increases pressure as needed. They said simply call that number if anyone has any questions.
I told him I can now work at a lower rpm in 4WD and it won't spin tires, it just has more torque and he said that's exactly right.
More hp & efficiency means more power and less fuel used (efficiency).
Any questions simply call the company. All I know is it's money well spent and I'm happy with 30% more power.

It is just bumping the fuel rail pressure.....read about it.

I did:
This diesel performance module is designed for fuel economy with up to 30% increase in horsepower and fuel savings up to 10%-20%

Adjustable with a three position switch

You can adjust the power on the fly, Stock, +15%, and +30% HP

The module does not flash the ECM, instead it receives the data from the ECM, optimizes the signal to the engine improving the fuel efficiency and power

These savings ensure a quick return on investment so you can enjoy greater efficiency and less cost

Plug-and-play connectivity means there is no need to cut, splice or modify engine wiring

From what I read, the cheap way of adding fuel is lowing the voltage from the fuel rail sensor. The ECU then bumps the pressure up to compensate the faked low pressure signal. There is normally a pop-off valve to protect from over pressure but they don't survive being popped often. Some sellers of chips have stopped selling these types.
