Before I make a mistake. Can I advance a camshaft 1 tooth and not effect the E38 58x and 4x cam gear signal. Or should I put an adjustable cam gear and line it up dot to dot! I programed my buddy's car on the old 350 with an 97 vortec and worked flawlessly. Learning gen 4 ls and loving it! Just this is a stumper before I screw up. Thanks for any help I can get! LS9 Cam is the target. Has no advance in it. I degreed the cam 1 tooth and it looks to be 7.5 degrees of advance. Took extra time and looking at option.
