Mack_Dog Posted March 26, 2021 Share Posted March 26, 2021 Hello fellow mack truck lovers, so my question is there any performance upgrades for the MP8? I know the dealer can up the power by 50HP but they will charge me 4-5.5k(technician info) which is STOOPID expensive for what ill be getting! I know i could also go thru the body builder and have them make out a 800hp but i wanna save that as last resort. Bully, as far as i know the only one, makes a turbo manifold too. This will be a slow-ish process and i know my transmission will be limiting me as well. Any advice? Thanks in advance 1 Quote Link to comment Share on other sites More sharing options...
