I am fairly new to tuning but I think I have reached my max without a Wideband kit. I have a 10 Sierra 6.2 and I'm assuming I need 2 Wideband sensors one for each bank. Is there a good kit with 2 sensors or can I modify a single sensor kit to work with 2 sensors and just buy an extra sensor? I just want it for data logging basically I don't really care to have a display. I'm wanting to spend less than $500. Thanks
