i have an 2002 duramax with 230,xxx whch i have owned since she was new, but i just got done putting in the banks big head turbo actuator, cold air intake, 4" turbo back exhaust, and the edge cts evolution tuner. i still need to install snow performance stage2 water/meth injection and banks inner cooler. but before i do that i have a fuel issue because i barely get 10 mph and according to my tuner my injector balances are all over but once to temp they very from -3.8 all the way to +4.8. They stay atleast 1.4 or so different so none are they same. I have read it could be the fuel regulator but im lost and about to just fork over the money for a shop to deal with the head ache because nothing is worst than working on tractors all day to limp my duramax home and chase the bugs. please help its my day off
