KKRT Posted September 8, 2017 Share Posted September 8, 2017 I just joined the forum after purchasing a 2004 CH713 with an AC 427 engine. I pull 20+ ton trash trailers and this CH will not pull up hill like the other guys. Two questions to the Mack Team; 1. How can I delete the EGR to make it a regular E7 427?, and 2. How can I get more power to pull them hills? I know these topics may have been address in the past, but I will appreciate any feedback. Thanks Quote Link to comment Share on other sites More sharing options...

I would not use butt connectors, solder. Edited September 8, 2017 by Mack Technician Quote Link to comment Share on other sites More sharing options...

dcrow Posted September 9, 2017 Share Posted September 9, 2017 I just installed the performance module yesterday and I did notice a difference today. Only used it for 1 day so far so I dont have any fuel millage results yet and no dyno test but it did have more power, not a ton but was there. I will post millage results when I have them 1 Quote Link to comment Share on other sites More sharing options...
