I took the movement speed bonus from the jetpack and added it to the surf board plugin, So if you want a speed boost to help you surf difficult maps you can simply get the surf board rather than an ugly jetpack
amx_createnpc - This will open a menu to spawn a NPC where players can interact with it to get a surf board (optional)
say /surfboard - a chat command to be given the surf board
say trail <color> - type trail blue (example) to get a blue trail ( the plugin will give you a random trail when you first get a surf board )
The color names can be prefixed with "light" or "dark" Example : trail light blue - or trail dark blue You can find a list of names in the amxmodx/configs/colors.cfg file.
sjp_min_speed 400 - min speed required before the speed boost is activated
sjp_max_speed 1200 - Max speed possible with the boost
sjp_thrust 10 - Amount it will thrust you forward once you read min_speed 400
