Experiences with DISA and Turbo?

My turbo setup has been going for a while now, though there's a random strange behavior. Every once in a while if I load from low rpm, the motor builds boost but feels like its falling on its face. For kicks I set the DISA to always open in the tune and the hesitation feeling seems to be gone. I notice almost no loss in the low end, if anything it spools a bit quicker. Has anyone had a sticking DISA under boost? Also, if permanently keeping DISA open through tune safe, should i remove the DISA and gut the flap out, or just try to remove the DISA altogether?

sort of. It's kinda stupid trend imo. Yes, if you're scared it's going to collapse and you're down to lose torque and spool without picking up power, this is a real solution. But over over 800whp has been run through the stock intake with DISA. It just can't be 20 years old with 300k miles. It needs to be fresh or freshly rebuilt with loctite.

yea, if you're gonna delete disa, might as well do this, at least make better top end, have a sleeker, less busy single plane intake with better injector angle.
