We've got an 08 8010 that was a complete dog. Couldn't get 3500bph in 20% corn without powering out. The dealer downloaded new software, and injector harness. They logged everything and sent to mother C-IH who said nothing was wrong. They brought out a 7010 that ran circles around it. Well it turned out that is was just injectors. Now runs like a raped ape and can get 5000 bph. F'n awesome. We do have an exceptional dealer who let us keep the 7010 while they worked on the 8010. They spent a lot of time on our problem and took care of it. Would highly recommend Mitchell Equipment in Atkinson, NE to anyone.
