supradanturbo Posted July 6, 2016 Share Posted July 6, 2016 I've got a boost issue. Only occurs when below 4k rpm. And under load. Ie. Launching with the histall. It builds rpm then as soon as i let of the brakes and floor it. It Jerks and hesitates. Once above 4k it's fine and has no issues. I have smoke tested both sides and no leaks. I have also swaped vsvs and still doing it. I changed the ebv vsv and this seamed to solve the issue for a few days but it has come back. Any help would be much appreciated.

GSR2007 Posted July 6, 2016 Share Posted July 6, 2016 Having a similar issue myself been told vsvs,coil pack clips among other things I'm going for a complete single setup and new clips and anything else that looks fragile along the way I'm no mechanic so reliability is a must Link to comment Share on other sites More sharing options...

GSR2007 Posted July 7, 2016 Share Posted July 7, 2016 Mine sometimes holds back when second turbo is due to come on jerking and hoping so I let off and go again 9/10 that works fine but id still like to rectify the issue because it needs to be 100% Link to comment Share on other sites More sharing options...
supradanturbo Posted July 10, 2016 Author Share Posted July 10, 2016 I ran at santa pod over the weekend and not only does the car hesitate at lower rpms. It also is gereraly not smooth through out the rev range. Link to comment Share on other sites More sharing options...
