rl Posted October 4, 2009 Report Share Posted October 4, 2009 With no line it will make as much pressure as it can before exhaust pressure forces the WG open, which in most cases is a LOT of pressure. Quote Link to comment Share on other sites More sharing options...
DTM Brian Posted October 4, 2009 Report Share Posted October 4, 2009 does anybody know what the yellow spring in chads kit is supposed to make?? we were making 12 lbs of boost now were only making 6, we found the vacum line to the wastegate was off, should it make boost with the line off?? Boost should continue to climb without a wastegate line connected. If boost has gone from 12 psi to 6 psi then I would take a look for exhaust leaks before the turbo. I hope you have a wideband sensor on the car. The tune I provided was just to get the car up and running. Quote Link to comment Share on other sites More sharing options...
