Yeah the stock tach is kinda slow. Allens got mine shifting at 5900 1-2 and the tach shows 5700 and the 2-3 he has set at 5800 and the tach shows 5600. I was actually on my way back home when I noticed and called him up and he said the tach was kinda slow but he would re-flash it if I wanted so I said I'd live w/ it...Zed
