I run a WOT switch myself. I am a very good and seasoned driver, but everyone makes a mistake here and there, and mistake on juice usually isn't a good one, so I would just let off the gas a tad on shifts like I do. It still nets me almost 2 full seconds in the 1/4. As for the Fuel line, I have a dry kit and have never worked with Wet so I can't help you there. Good Luck and Happy Spraying.
