JamieS Posted June 6, 2011 Share Posted June 6, 2011 My technical knowledge is a bit limited, so this could be a bit of a beginner question, so bare with me! Just had the car back from AFR after having a detonation problem sorted. Drives lovely, no problems. When I left there, it was hitting 1.2 bar on high boost without any problem, but since then it's dropped back a bit to around 1 bar. Neither AFR or I have checked the exhaust system, but the previous owner was nice and vague and told me there was a restrictor ring for 'about 400 brake, so around 1.2'. Does the fact it's pulled back to 1 bar after being set to 1.2 using my Greddy boost controller indicate that it's probably got a 1 bar restrictor ring fitted? Thanks Quote Link to comment Share on other sites More sharing options...
