AFR data viewing, in real driving situations, is the new standard for tuning. The DP O2 Chamber is the best tool available on the market to allow a user the ability to easily install a 18mm wideband O2 sensor. Competitor products which are installed going up the exhaust pipe simple do not provide accurate readings.
The DP O2 chamber should be used in conjunction with the DP Exhaust Probe and requires the installation of a Nutsert.
