you can keep your usdm ecu and ap and run with no avcs but the results are not stellar

or use the jdm ecu (that will not pass us emissions testing because the ecu will not talk to the test equipment) and get an avcs wiring kit from iwire or the like , opensource tune , no ap

plug us ecu back in for inspection time , you could opensource that as well and sell the ap

btw , If you're still on the stock turbo from your 2002 wrx , I have a cheap twinscroll setup listed in f/s here

I知 not familiar with the twin scroll setup. I like the idea of the vf48 due to it being used on sti痴. And I知 not looking for too much power. I致e got pinks already and really just want to max out the pinks with the vf48 and see where that gets me. I知 already happy with the power, just want to see what the AVCS is all about, with slightly bigger turbo and more IDC, right now WOT I知 at 76% with the jdm turbo, and I知 sure there is more room to spare
