RR, I couldnt help myself with all the mods in one big splurge, plus it was cheaper to get them all done together.
My local REVO dealer has changed recently, and the new one seems to think its the TWintake as the main culprit. As i say i have to go back for more logs once updated map has been on for a while and got some good quality super unleaded through system. Trying to rule out poor quality super too. Normally i run BP 97RON - nothing higher available here. Sometimes use Topaz if caught out.
