Thanks Boucher for the info on your truck.
as far as not to worry about pressure drop,,, well, thing is, sure you can turn up the boost pressure, but you need to ask yourself, what is really going on, why is it loosing pressure & what is the result of increasing boost pressure?
I have read, for every 90 degree bend (intercooler piping) you can loose 1/2 to 1 psi per bend.
So when for an example you set boost pressure at 10 psi and after the install, pressure dropped down to 7 PSI.
If you actually took a temp reading of the turbochargers compressor discharge initially @ your original 10 PSi (before intercooler install)lets say it was 200 degrees (F) then, after the install of the intercooler, you then adjusted your wastegate to get an additional 3 psi, if you would have taken another compressor discharge temp reading, it would have shown a temperature increase & you would have seen , say 235 degrees (F), (just as an example, those temps are not accurate, just throwing out some numbers) but you would have seen an increase in temperature, and your turbocharger is working harder to produce the same boost pressure.
What am I getting at?
Not trying to make anyone look bad, no, just trying to say, keep your bends, gentle, keep the bends to a minimum, get the best flowing & efficient intercooler you can afford.
All intercoolers are going to have pressure drops, but there are decent intercoolers & poorly designed intercoolers out there.
So do a little research.
Example of a better designed same side inlet & exit intercooler. This one states: "PSi Drop under 0.2. Other Intercooler usually drop 2 Psi Some are More."

Note: the air enters one end, goes to the other end & the air has to make a 180 degree turn for the air to come back.
This one states: "Pressure Drop:2~5psi@35psi; 0.2~0.5psi@15psi"

I am bad at trying to explain things, sorry.
