Every tuner guide made is completely wrong. Dont look at them for any value. People that "tune" are also not experts in any form... the guys that write the HPT software in fact have no idea what they are doing unless they spend significant time looking at complicated de-compiled assembly code. Even at that point its hard to see a clear picture of whats going on.

Where this "tune fuel trims to 0" idea came from is just stupid if you think logically about it.
How do you tune a cammed w-body then? Lots and lots of air being drawn in just for example.

How would you get my issue dialed in? If you are adding 6psi or so more than stock then there will be an adjustment needed. Like wise bigger injectors will cause trims to jump.

Is this your own little secret of the right way to things? Not willing to share?
