Deere lists the 9L motor on their website at up to 400hp at 2200rpm with the tier III motor. So I would say that a 10% chip would be safe IF the internals were the same. If the pistons are the same part #, I would feel safe.
Can you chip these without leaving a electronic fingerprint anymore?
You have me curious on this. I looked up the replacement piston liner kit and found that part # RE530459 (includes pistons, rings, cylinder liners) is in common with 8130 - 8530's, and both the 96 and 9770.
I have little reason to doubt that the 400 hp motor has the same parts...CRANK IT!
Really? Or is that just mother deere blowing smoke up yer @ss. Take a Deere 13.5L engine putting out 375hp, then look at the 9630 with a 13.5L engine putting out 530hp, the same block and cooling system. Something I'm missing here?
No doubt about overpowering the machine.
You need to use common sense whenever you are using any mod to any machine.
Most sales I have made in the past 18 to 24 months have been made for fuel economy increase as much or more than hp increase.
Plus I have made another arrangments with another mfg to sell there product,which may be more economical for the high cost modules.
JDmanitoba i agree with u john deere wants 15,000 dollars to go with a bigger combine 9670 to 9770 when all it is is horsepower, im really ticked they go into the computer and just flash the program and poof theres an extra $15000 dollars, makes me sick
