Ok I just got done taking my magnacharger off and I put the new tune on that Allen mailed me. My truck threw a code P0315 - Crankshaft position (CKP) system variation values are not stored in the PCM memory
It's runs fine so is it just the tune?

It is a crankshaft position relearn, common occurance when swapping PCMs.
If it runs fine, then it is okay. Sometimes they run like crap with that code, which isn't okay.
I pay the local garage $20 to perform the relearn procedure, it takes maybe 5 minutes.
Gone, but not forgotten!
Thanks for the help I got it done for freeat the local chevy dealer.
Also Nelson performance returned my call very quick to help me out.
