I started off my boost journey with a procharger D1SC kit with the twin intercoolers. And my boost gauge would read 15 ish lbs of boost.
when I upgraded to a front mount my gauge went from 15 to 8.
my friend told me that the gauge would go down because I had more room air with the bigger tubing an intercooler.
but I have another friend telling me that the front mount has restricted my airflow now that boost gauge has went down.
So what I need to know is do I need to put a bigger intercooler in it. The current one is 24x12x3.
Chang the pulley out to make more boost?

What engine? Compression ration? Pulley configuration?

Is that the core size, double ck for a boost leak.

Stock displacement Ls1, just honed the block and put forged internals,

the pulley configuration is stock except with the procharger

Yes that’s the core size

I would say that you have less restriction with the larger intercooler as you boost decreased. I have a 390 cubic inch motor and my D1sc is pushing 14-15psi through a front mount but I'm nearly maxing out the procharger with the 7.65" crank pulley and a 3.55" blower pulley.

boost is just a measurement of restriction.

There's a good chance you are making the same power, if not more, at a lower boost level. That's a pretty significant drop in boost though.

You can go from a stock cam to an aftermarket cam and drop boost, you can put on better cylinder heads on it and drop boost.

Is there a rag on the intercooler? If not, send it back! Yes, boost is a measurement of restriction, to lose 7 psi is ridiculous. Monitor pre intercooler pressure and see what’s up.
