Track down the original owner.

I'm debating on tracking down the original owner of my truck or taking it to a diesel shop to figure out the mods that are currently on the truck. I began looking at my truck the other day because I'm planning a twin turbo build and there is multiple things that are not stock that make me wonder what is on the inside of the engine. It has a lot of banks stuff but the thing that I noticed the most was the air intake manifold. It seems to be aftermarket because usually they are flat if I'm not mistaken and mine is raised. Also when driving my stock turbo can reach almost 40 psi with no issue and seems to pull hard without issue. the other thing is the guy who owned the truck before me always ran the banks six gun on level 6 and it's been holding up fine it seems and has 0 blow back. What do you all think I should do and any information on my 2004.5 cummins and how to build it reliable would be much help. My next mods are headstuds, fass 150, and smarty s-06

Since it has a lot of banks stuff makes me think it's stock as the po probably wasn't too educated on performance mods. I'd just assume it's stock. The stock he351 is safe up to around 42psi. With a good tune they will hit that easily. Not sure what you mean about the intake manifold? But aftermarkets can be had for around $100 so it probably doesn't mean much.
Yea that's what I thought also but people say banks is better than stock. Only banks stuff is upgrade intercooler, six gun tuner, monster exhaust, and high ram intake. I'll take a picture of the intake manifold and I'll try to explain better. It also has a fitch fuel catalyst system on it.
