p0103 after MM3 install

[007]

I did this morning they're working on it. You have same year truck and had same issue highly unlikely we both have A wiring issue after flashing... Got to be tuning!

I thought was odd I had the CEL immediately after tuning but the fact that we fix cars for a living, I've seen weirder things happen that are totally unrelated.
I'll continue to check things on my end and hopefully HPP looks into it also and maybe finds something.

I might flash to my old tune tonight to see if it goes away.

Let me know, when I flashed mine back to stock I got P0102 code, MAF sensor circuit low instead of the P0103 code.

Ok, so I tested everything. Verified PCM wiring for shorts and opens. Flashed the truck back to stock. After PCM was returned to stock no p0103 or p0102 codes. I then called HPP and talked Brandon who told me he had talked to you this morning. It appears the problem is in the tune.

He told me he would have Jonathan send me an updated tune. I'll let you know what happens

No, I talked to them twice yesterday. They said Jonathan would look at the tune files today. I plan on calling them here soon.
Have you talked to them today?
