Colder intake air is free HP.

This isn't the hoopty pb build lol I got good stuffDuct tape and RV poop tube?
I added dual battery and my ac gets in the way over thereIf you have one battery I would get it over to the DS and punch open one of those knockouts on the rad support by the headlights. Assuming your truck has those, I know mine does.
First things first, did you go through an properly setup the parameters, what cam setting did you use? Did you properly adjust your IAC? Did you verify the TPS is zeroing out? If the rpm is low is your target rpm set too low?
And if your timing wasn't touched I don't see that being a problem
So back to the air question. Would pulling from right by the battery help at all? Gets it away from the engine, headers and fan.
