Hey guys,

Playing around with the EFI Live on my friend's truck showed these balance rates:


Cyl 1: -2.0
Cyl 2: +3.7
Cyl 3: -1.09
Cyl 4: -2.25
Cyl 5: +2.15
Cyl 6: +1.7
Cyl 7: -1.12
Cyl 8: -1.02


What do you all think? The truck has about 190k on it and it runs great. No smoke, perfect idle, zero problems.

Looks just like mine, and same here, no smoke, no fuel in oil, so Im not worrying. #2 is getting questionable but +/-4 is the "mark" in park. The rest of mine are +/-1.5 or less just have one that intermittenly goes over 2.5. I wouldnt worry if theres no other indication of a problem. Is it an LB7 truck or newer?

I'm sorry, I didn't realize I left out the truck info.

Yes, it's a 2002 LB7. I am worried about #2 as it did hit 4.0 a couple times. The numbers I posted were the averages.

Mine hits 6-7 on that one injector sometimes, but more often than not it stays right around 2.5. If I run the shit out of it on max effort it gets better. I run additive almost every tank and it seems to help. Im just prolonging the inevitable, but until there is another indication I have a problem Im not worrying about it. Your situation is alot like mine. I wouldnt worry until you start seeing another issue show up.
