Im looking for possible causes for my trims being off bank to bank by as much as 6% sometimes more. This makes it impossible to try and dial trims in close to zero. TVS2300 came with marine Delphi 42lb injectors issue was there, today I installed a set of deka 60lb, still there a little worse then the Delphi's. replaced o2's, no better, new gaskets under blower, no better, installed different heads PRC STAGE 1 317'S no better. plus plugs, wires, coils, no change.
Im looking for ideas on what to try. Im willing to go out a buy some Injector dynamics if this is just inconsistent injector function. thinking about just going OLSD and be done with trims. mods are 6.0,tvs2300,gt2-3, kooks LT'S, 1 bar maf but going SD but I was hoping to stay CL.
