will the accessport be enough to tune my built ej20 w a stroker kit from jun, and cobb head with jun 272 cams if i went for a gt40r turbo kit? or do i need to go something like a fully programmable ems like aem or hydra

The main thing you'll run into is the 300g/sec limit on the wrx ecu. You'd probably be better off with a speed density based standalone such as the autronic or the aem ems.

isnt the hydra standalone?

UTEC does SD as of the 5.8 update.

The AP would definetly work.

nice. i also heard the ap will pass emissions as for the hydra and the others prolli not right? cuz of the open maps?

The AP will work with special tuning maps, no need to change.

nice i think im going to pick up an AP 2 soon. hopefully ill be able to pass emmisions with that haha. if not w.e. ill find a stock downpipe for it.

the ap and EcuTeK use the OEM ECU so if tuned properly they can be made to pass OBDII scans by defeating certain DTC's (like missing 02 sensors, EGT sensors etc).

Standalones don't even use the ECU so no they will not pass an OBDII scan.

from what i hear speed density tuning is in the future of the APv2, but i'm not sure i would want to wait around for it if i was you... guess that depends on when you plan on doing your build and therefore when you will need the EMS.

yeh i think im going to try out the ap2 with street tune and tune out the bugs. hopefully that will work if not ill use my freinds stock downpipe...
