They really don't spool that loud due to low boost. There really isn't a way to make it spool louder.

There is a resonator in the intake that you can remove. Adding a 4'' exhaust will allow you to hear it out the tailpipe a lot more. But it wont ever sound like the new diesels.

Or you can put a really clogged and dirty air filter in and it will sound like a new diesel

I have a high psi spring holding my wastegate shut...the turbo controller arm broke in half (idfk how) but I just have a spring hooked onto my intake holding the lever forward, very hobo fix but it builds right around 12 psi of boost and it is louder than any 6.5 with a GM-4 turbo I've ever heard. Comparable to the turbo noise of a 6.0 powerstroke! It turns heads in town

IronBurban's Sig:1995 GMC 2500 Suburban 6.5 turbo diesel. Custom intake, pmd relocated, #9 resistor, feed the beast mod, homemade "turbomaster" 12psi, straight pipe 3"-4.5" tip. (Next mods include 80hp chip, marine injectors, and 4" exhaust with 3" down pipe and 2 1/2" x-over, and hx40 turbo)

Ditch the POS stock turbo and get yourself a bigger better turbo. You will have more turbo then you can handle.
