SOB! P0123/P0223
Some of the mods and background:
2012 5.0, Roush TVS2300, 82mm pulley, 47# injectors, JLT CF CAI, KB BAP, Lund Tune.
I'll try to make this short....Car ran just fine, but I'm swapping everything and putting it on a 2013 and getting rid of the 2012. Pulling everything off the motor, de-pinned and removed the BAP. Installed all the stock crap from the '13 on the '12. Uploaded the stock tune and now the frick'n thing won't start. Pulled these codes: P0123/P0223. I looked them up, search this forum and another for troubleshooting. I checked all the connectors and they look fine, checked where the BAP was and the re-splice is fine, tried resetting the ECU, I even re-loaded the Lund tune and then returned it back to stock and same shi*t. What's the deal and the fix? Any help would be great. Here's a video:

just googling the codes says its the throttle position sensor. Is your stock tune corrupted possibly? do you have it saved on the computer?
If i was you i woul try calling lund and requesting a stock tune if possible, or if worst comes to worst, id have it towed to dealer and have them troubleshoot and upload the stock tune and see if that works

Stock tune is automatically downloaded to SCT prior to loading a custom tune, but I did think the same thing about the stock tune. Great idea about getting a stock tune from Lund.

It's a throttle body wiring problem, according to the FoMoCo online maintenance manual website.
Check the wiring to the electronic throttle body. Your plug is loose or there's a wire that's not re-pinned correctly after you removed the harness extension.

I had a buddy send me pictures to compare the wiring order. I'll check it again to make sure it's all "Tight like a Tiger"..LOL

connections are good and not loose.
Waiting to hear what Lund has to say.
Wouldn't there be a chance of blowing the motor starting it with the blower tune?

I know this may be simple. But when I had my V3 blower, all of the sudden my car wouldn't start. I had it towed to ford. They couldn't figure it out and basically stopped working on it. I started to look at everything and noticed that when I made a quarter turn with the key, the fuel pump wouldn't start.
Turns out the Kenne Bell BAP has a 20 amp fuse that blew. The fuse thats attached to the BAP. It shut the fuel system down. I changed it and it fired right up. That was my Achilles heel on mine.

I can't see how. It will probably run really rich until closed loop, at which point it will start pulling fuel and eventually set a code.
