Ok i'm having a lot of trouble finding the correct shift points for a cobb stage 2 setup (tbe and OTS cobb stage 2 and silencer delete). I've done a search here and nasioc and I can't find a definite answer so I tried a lot of different things, 1st and 2nd i always take to redline, 3rd to 4th i've shifted at redline, 6700, 6500, 6200, 6000, and 5500. 4th to 5th i tried the same rpms as 3rd to 4th and I can't break a 13 flat run or a 12 second run? What's a good recommendation? So far my best time was 13.2 using 1st to 2nd redline, 2nd to 3rd redline, 3rd to 4th at 6800 and 4th to 5th at 6000.
