Bought a N.H. T9050 H.D. scraper tractor last winter with 2000 hrs. Tractor runs fine, shifts fine but powers out. Acts like 300 hp not 485hp. New filters, new fuel pump,new pipe between turbos, old one was cracked, mechanic says fuel pressures are in range.Does not smoke. Running at high rpm with next to no weights, I keep shifting down gears but eventually it just powers out. The tractor should just spin out rather than power out. Is the ECU the problem? Any advice please.
