Hi,

Can you tell me how you are managing with the right-hand bends, I seem to be scraping the road before my floorboards

Can you feel that torque dip? You need to up the compression for those 585s.

I am no tuner, but that AFR graph looks all off. How much time/how many runs were made during this Dyno?

Default 2016 FLSTFBS +117 kit Dyno Sheet

Just tuned with SEPST (SERT) and 117 kit (injectors, TB, 259E cams, etc) and SE Cam plate with high volume oil pump. Cobra 2-2 exhaust and 58mm backplate added to the stock Ventilator Elite air cleaner. I expected more from this build. Maybe lost too much due to 2-2 vs. 2-1 exhaust? Comments welcome.

looks like you could drop a main jet and cut back the accelerator pump. Needle effects cruising AFR and dropping it will make It richer at cruising
