bumping an old thread as i'm after some info on the AVCS unit in the EJ207's (mine in particular is an MY03 JDM EJ207)
this is my most recent dyno chart from ASG. Sean thinks the funniness in the power band is due to the AVCS not working properly and it may need a clean our or something. Is this a hard job to do? Has anyone else had a similar problem and was able to fix it by cleaning out their avcs solenoid?
