Surging with small shot?
 

Running a HSW dry 75 shot with there interface no window switch or fpss. When I spray it the wideband will fluctuate from 11.1 to 12.0 and the motor will surge. Im running new tr6 plugs gapped at .036, bottle pressure is at 950psi and is mounted correctly. Bottle weighs 22lbs any ideas? :confused:

Fixed it! The WOT switch went out of adjustment and was clicking on and off...:rolleyes: I waisted no time throwing in the 100 shot jet. Holy crap! :eek: Im temped to put in a 125 jet but im already pushing the limits of the glass A4 and rear. :(

congrats

Your not pushing the limits of the rear, unless you are hitting it from a dig. Up it to a 150 and do a highway roll :D
