New hemi install total cost

$2350 for an EFI system???
OUCH!!!

But yeah there are "hidden" costs
Such as that "corvette style" fuel filter/regulator is only $30 but the connections/adapters people use to get it to -6AN will run you $50 for the set.
Then of course, everyone wants to run braided instead of rubber EFI hose.
That's like $5 per foot.

I checked the beginning of your build post and MAN seems like you went through it in the early stages.
I'm sure you have a fire breathing dragon by now tho.
Not $2300 exactly
EFISource Gold Box and harness= $1295
92mm cable TB=$370
Wideband O2 w/indash digital readout=$250
80lb/hr Siemens injectors=$250
DW300 pump=$130
Fuelab reg and gauge=$130
Magnafuel 10 micron lifetime filter=$80
Tanks Inc hanger for intank pump=$80
Homemade surge tank with trap doors in tank=$90
So yeah it wasnt junk yard scores like some can get, but I have WHAT I NEED for my power level and driving style which is far from a stock retrofit. I can add a dry 250hp hit of nitrous and have the existing support in place. I am also set up to go to E85 in the event I decide to.
