Dual quads versus big hammer!!!...
I took close to a 50 mile drive out in the country little highway mostly cruise speed... Of course without question a few wide open throttle shots like in 3rd gear and a little bit of City...
The wideband was showing hi 12's and low 13s at Cruise... It was looking like 11.5 or so at wide open throttle..
still some small flat spots at mid throttle but really this was just to kind of enjoy the car for a little while and get out of the house... I filled it up before I left and filled it up when I got back and used about four gallons for the 48 or so miles..
I checked the passenger side plugs again and they all look pretty much like this one...
