Your 9610 has a mechanical fuel system. Therefore, all you need to do is turn up the pump. Unless of course your pump is already maxed out and if so, that 466 is operating with way too much power and if a lack of power is the problem, then you've probably damaged something already. Otherwise, don't mess with a chip for an engine that old, if you can even find a chip for an engine that old. Power chips are designed to work with electronic fuel systems that are designed (by law - the EPA) without the ability to be turned up mechanically. A power chip is nothing more than an inline resistor used to re-map an engines fuel delivery for optimized performance. This re-map takes place within the electronic fuel system's software, a feature that a 9610 does not have. Besides, having a mechanic turn up your pump on the side will be cheaper than buying a power chip, alot cheaper! The chip just for my pick-up was $600. You can just immagine how much one is for a combine or tractor. I saw one for a cummins engine that went for $1500.
