So I cant just drop in a PCM? I need to perform other steps in order for everything in my car to work correctly?Originally Posted by Sabrewings

Normally yes, you can just drop it in.
But seeing as your having problems it would be best to do a CASE learn and see if the problem is resolved by it.
However.... I don't see how it would effect your gas gauge not working correctly.

So I pulled the Overkill PCM and reinstalled my factory one ( I kept it). and my fuel gauge returns to normal
Well I sent a email off to Will and will ave to see what he has to say I guess.
I am lost

Honestly sounds like something was done incorrectly with the PCM then.

Or the PCM is faulty.

When i installed mine i had no problems. I did read somewhere that there is more problems with the newer model GP's and overkill pcm's. When i got my pcm i emailed Will and asked if i needed a "case learn" he said only if you get a check engine light, and i didnt. So i guess im in the clear?

Never heard of that happening with a pcm.
Let us know the outcome!

Like I stated above Will at Overkill thought-
It seems as though this is an issue with 07s using the older PCM box and isn't a faulty PCM. GM has likely changed how the fuel gauge is calibrated for the 07 model year.
I would think that fuel calibration would be the same for 05,06,07???
