More power

[Severed TIES toy]

Ok I have a question for all you guys.... maybe you can help me. I have an international 4900 with a DT466 mechanical, Im looking to get alittle more power out of it. I runs great on flat ground but is lacking wile pulling hills. What are the most cost effective and easy ways to boost HP.

Thanks

Go to the escappees forum and post this same question on the HDT forum, John W Morgan has a bunch of experience in cranking up the IH DT466
