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.

I would not use butt connectors, solder.

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 https://www.bigmacktrucks.com/topic/50947-need-egr-retrofits-or-delete-kit-for-ac427/#findComment-379259 Share on other sites More sharing options...
