I have a TSS 98 with a 58/42-.36, 800 RMK 159 2.25 ,19/41 and 43, SLP single Mbrp or Thing can , high flow and intakes, just put pipe and air mods on , usually just change weights and jetting when I go out west and runs OK, now I got the mods so Im wondering do I need to change the springs and helix, and if I do per SLP chart, it says that I have to change angle on Helix as I go up, or do they mean the spring set? Will I notice a difference from the Helix and springs? Compared to stock.
