RS VR6 0 Posted June 25, 2007 What do you mean by the dip feeling a little "strange"? Under full throttle acceleration the "dip" is barely noticeable. If the flapper is opening...the VGi should be correctly installed...or at least wired correctly. The flapper should open in a clockwise direction. Double check your timing. Make sure the marks on the crank line up with the marks on the block and cams at top dead center. The purpose of the VGi is for the midrange torque not horsepower on the top end. I have the same setup (VGi, 260/264), but I have a VF supercharger also. Quote Share this post Link to post Share on other sites
dr_mat 0 Posted June 25, 2007 Almost looks like your VGI is staying shut.. The peak at 4000 is about right (it comes in earlier with standard cams though), and you have the normal peak at 4600 ish, but you're missing the second peak that occurs in the mid-5000s. Are you having fuel supply problems? Got any dead sensors? Scanned the ECU error codes? You might have a cam position sensor fault? (Did you transfer the trigger wheel to the new cams?)
