Guest ON3GO Posted October 19, 2004 Share Posted October 19, 2004 ok right now im driving a Lexus SC300 with a 1JZ-GTE swaped in. the ECM has fuel cut at 15psi, and it should be limiting the turbos to 15psi and no more. now the problem is its not hitting fuel cut and its boosting 20psi.... not spiking either, staying steady. boost gauge goes to 30psi also, so theres room to read more.. its pretty much 100% stock also. any ideas as to why it would be boosting above 15psi and still not hitting fuel cut. mike Quote Link to comment Share on other sites More sharing options...
john kosmatka Posted October 19, 2004 Share Posted October 19, 2004 Previous owner disabled fuel cut? Either that or a faulty switch. Watch for detonation. Quote Link to comment Share on other sites More sharing options...

Hugh Posted October 20, 2004 Share Posted October 20, 2004 Hmm... thats peculiar. Those things ride nice, though, ha? I got to drive a Soarer 1JZ-gte in Japan when I lived there. My buddy's wife's ride. It was sweet. Quote Link to comment Share on other sites More sharing options...
