Weak fuel pump or weak hpop?

So for the second time now as I am getting into it while merging onto the 4 lane I get a shudder. Its not drive line, I am pretty sure it engine related, feels like a fuel issue. Like the injectors aren't getting enough oil, or not enough fuel. Both hpop and FP are original the the best of my knowledge, 290k on tbe clock.

Mods are in my sig, I run the TW in street 99% of the time.

Any thoughts?

Install gauges on both to verify while driving. Or use a scan tool to tell you HPOP output and duty cycle. What is boost doing while it's happening?

my geen 95 did the exact same thing w/ stage ones and Tw tunes. converted to elec. fuel pump and aftermarket regulator problem solved. I now have stage 2s and use the same fuel set up so its worth it to do the conversion now instead of later with the 2s u want.

Boost was running between 10-12psi...

E-fuel is the next thing on the list... I am pretty sure that its the original unit.
