Hey guys

I have a my99 wrx audm with fmic vf34 and turboback exhuast; i have just installed a jdm v6 sti ecu j2 and after changing the required pins over everything starts and runs well feels much more responsive at lower rpm.

Only issue is that before the ecu swap my standard e3 ecu was running around 15psi and now with the v6 sti ecu im only getting 12-13psi, i am not running any boost control mods although i have manual boost tap lying around somewhere which i will use if needed.

Has anyone else had any experience with this maybe its normal and i should just wind it up! i just presumed with the sti ecu it would run more boost.

Any help would be great

Thanks
