Hi guys,
got a 2008 specB Legacy GT 6MT with Ej20Y and TD04HLA - 280HP. I got a fully 3" exhaust system with a HKS catted DP and a 340L/H AEM fuelpump, NGK 7er iridium sparg plugs and a highflow airfilter in OEM housing. I just want to run my exhaust system without any issues and a bit more boost, which is within a range that does not put too much stress on the engine and what my OEM injectors allow, I thought about 17-18PSI.

Could anyone provide a maching map? If you need my current maping I could provide it.

start with your stock map and then reduce the wastegate duty until your boost is back in line.

If you want to run more boost then bump the target and increase the duty - always keep an eye on your wideband and knock readings when doing this to avoid problems.
