SR20DET Hesitation

[240msh]

The motor is hesitating going into boost, but after will be fine, but still seems a little slower from when I had this motor in my last chassis. Im running the pbm highmount intercooler now vs the old isr setup I had, itll be super sluggish like an anti turbo for like 800rpms between 2600 3400. If I advance timing it gets worse, and if i retard it, itll slightly get better. Ive swapped out injectors, fuel rail, coilpacks, throttle bodies, iacv, intake manifold, all new gaskets on everything, vacuum lines, wastegates, exhaust gasket, coilpack harness, cam angle sensors, and spark plugs. Still does the same thing, it also wont go into timing mode unless i manually do it using the consult port and the nissan database. Even then itll still act funny like if its idling high, but cant find a leak anywhere. Ive sprayed cans of starter fluid and soapy water.. nothing. If anyone has had the same problem let me know. Motor use to run fine

Timing, Knock Sensor, and possibly issue with solid motor mounts.
