Blowing blue:((

[ford_cummins83]

I got an 04.5, been runnin the xcal2 on it with a buddy's tune ( wasn't made for my truck but it does work on it, but it's made for bigger injectors) its been on here about 6 months now, but when it's cold it starts up like crap, so this morning I took it off to see if it would start better, no difference, still crappy.. I got on the highway going 75, and when I let off the pedal a little it would blow blue smoke and start popping and it's giving me #4,6, and 7 injector codes.. I checked my my ficm power and it's putting out 43v, and ipr is right there with desired.. But since this tune was made for bigger injectors, could it be starting to burn my stock ones up?

Put the module back on, ran a self test, buzz test and everything seems to be fine, headed back down the highway and it's fine.. Why would it not like being stock?

43v means your FICM is bad

I put a new oil cooler on a excursion last night and it was at 38 and still running, but why is it running bad stock but not with the Sct

[ford_cummins83]

Just checked it again with the Sct on and it's 48v

you probably need a few injectors, it's not unheard of

[ford_cummins83]

That's what I was afraid of.. That or a ficm

[BeXtreme04]

The tune is making the ficm work harder and it just isn't up to the task... Anything less than 45v is a bad ficm which can cause injector codes and eventually failed injectors... Check your batteries, get your ficm rebuilt, and then worry about injectors if there are still issues.
