Hi guys, Just got my barely used 2013 250SX. I am familiar with the power valve springs (Red = Aggressive, Yellow = stock, Green = Mild). But I haven't heard of anyone testing the different ignition maps and never read any articles that speak of it until I read it in the owners manual just now. HAs anyone tried it with the cable plugged in (Agressive) vs unplugged (soft)? Also, what spring do most of you use? I also have the Kreft Power Dial which allows me to adjust the preload of the spring by simply twisting with my hand, pretty cool gadget. Thanks for your input!
