chrislucas121 Posted July 19, 2011 Share Posted July 19, 2011 Hi my car has all of a sudden got boost creep, the first two gears holds the boost at 1.2 bar then the other 3 goes off the scale! I have a mbc and in plumbed it and went off the wastgate and it was a constent 0.6 bar then I use the boost controller and it fucks up! Any help?? I have looked for leeks and nothing the only thing I can think is the wastegate don't work under pressure, I am getting a ebc when I get paid but any help?? Quote Link to post Share on other sites

DavidAshton Posted July 19, 2011 Share Posted July 19, 2011 Probably not enough load on the engine in lower gears to reach maximum boost pressure. Quote Link to post Share on other sites
