[QUOTE="Ouachita, post: 1849431, member: 16802"] That last paragraph is golden. Good advice. Many times the differences in horsepower rating with the same basic engine in different tractor models, are external to the core engine; size and efficiency of cooling system, fuel delivery and etc. Sometimes it’s cheaper (and better) for the manufacturer to use a larger than necessary engine and de-tune it for a lighter built tractor. If you want to “undo” the “de-tune” by “chipping” it, I turn it up slowly while minding the temperatures. Keep in mind that you’ll be operating with less margin. Are your temp gauges accurate?
