I have an X-charger and 42ís on my RXT right now. This off season I plan on adding a Rude 1 or 2 and an XS IC. I know Iím going to have to add fuel and start monitoring A/F ratios. Where is the best place to install the Oxygen sensor, manifold or J-pipe? Will I need to use a heat sink? Can the sensor be left installed or should it be removed after tuning? Iíd like to leave it connected so I can constantly monitor A/Fís. Donít know if it makes a difference but I ride strictly in salt water? What are you guys using? Recommendations?? Thanx!
