Put bigger turbos on...car makes less power
I recently made a few changes to my car including a new OEM fuel pump, 5" intercoolers and a new EBC. I also swapped my alpha 28 turbos for alpha 3076s. The car is making 20% less power on the dyno and my load is down by ~20%. The logs look good, the boost is stable and the AFRs are spot on.
Anyone have any ideas what could be causing this?
Thanks!

Do you have a fault code(air mass)in the DME memory since you are running mafless tune?

boost looks like its coming on super slow which could be a by product of a boost controller. your peak tq is 530 at 4300rpm, when i ran those on pump/meth at 1.5bar i was getting 530 at 4000rpm and 590tq peak having the gates crack at 13psi.
i would check the wastegates too and your boost control, maybe try running N75 for boost control.
