What chip for a 9860 STS

I'm running a 9860 sts with a 35 foot hydro flex head in 70-100 bushel winter wheat in very steep ground combine also has a hillco leveling system on it. We are running into power problems and are going to chip the combine. wondering if anyone has done this to a 9860 and what you are running? We are thinking of going with the ADS chip but are scared 30% might be to much in the sense of melting an engine? Any one have any input on this or other chips to look into?

HP 9000 works good on 12.5 jd engine. Have installed a couple on 9860 combines and one on a 7300 self-propelled hatvester. Only thing I would like to see on them is a switch to let you select between stock, a low power setting and high power setting like most of the other ADS boxes have. Not everybody wants a full 30 %. Alot of people would be happy with 15 %.
