I have bungs in both sidepipes after the collector merge. I use wideband system from Dyno jet with a gauge in the dash. The Dyno jet system has settable indicators for too lean etc.. and also data logs. I get throttle position, rpm, and AF ratio in my simple data logs. This is enough to take a drive, come back, review the log, and then adjust the fuel map (I run a Haltech FI). Very useful and easy to install and operate.
