502 pro charger removal, NO POWER
#15
With 625hp or so with the m-1's I doubt he was turning30 pitch props with 1.36 gears, would take some serious hp or have to be on a cat. Ecu's need a reflash closer to stock, probably rich as can be or something Mark at precision marine or Tyler Crockett should be able to do that, Smitty

depends on what was done when prochargers were installed...normal install on stock EFI 502 was no reflash but to jack the fuel pressure up with a boost referenced regulator to bandaid the system...so you need to know what was done..ECM's may be stock ?

I agree but the buyer didn't want them,and a shop took them off,guy backed out on the sale,and the shop don't have a clue what they did when they removed them.I'm just trying to help my buddy get his stuff running again.I know carbed motors but inj ones are a little tricker. Thanks JOHN SR
