Have you flushed your coolant? Reservoir looks a little gunky.
Also, I thought we were 370 cu in, not 372.
You could be introducing a lot of unnecessary turbulence into your incoming air with that ribbed tubing attached to the intake. It wouldn't surprise me if you were down HP vs. the stock unit because of it.
Also, do you notice high engine bay temperatures because of all the mirror-like plates in there? Could be enough extra heat to cause excessive aging of all the plastic hoses and wires.
Not trying to nit-pik too bad there Stan, just a few heads up
You certainly have your own style with regards to the SRT8.
