garcia26233 Posted August 8, 2011 Author Share Posted August 8, 2011 By the list I have-EUP #3.Does it have a miss in the engine?If needs replacement, make sure you get new bolts too.Yes it does. I bought a blixxton chip cause my new 460, replaced my 427, didn't cut it total pig. Well it only happens when put chip in full power otherwise it doesnt misfire. Do you still think it needs replacement or just don't run full power. Also see noticeably way more black smoke Quote Link to comment https://www.bigmacktrucks.com/topic/20103-8-3-code/#findComment-83390 Share on other sites More sharing options...
TOMD Posted September 3, 2011 Share Posted September 3, 2011 does it set code every time you put full power? I'm not big fan of power boxes because you aren't adding more air to help keep engine cooler.call me about getting engine to run better with out power box Quote Tom ~ Parts & Service SpecialistWatt's Mack Sales, Inc. 1-888-304-6225 Link to comment https://www.bigmacktrucks.com/topic/20103-8-3-code/#findComment-84957 Share on other sites More sharing options...
