Dyno comparison before & after install of aluminum LWDS + LW Pulley + grimspeed intake.
I would say no gain shows since the gain(after LWDS with 2 other mods) in the graph is minimum and each runs were done on different days.
My buttdyno claims no difference. Oh actually there is a difference which is NVH. I even tried to rotate it to find a better balanced spot, but no luck. It really drives me crazy on highway because back mirror image blurs due to this vibration.
