Finally got to test the Dart this morning and the readings are now rock solid and am a bit fat as expected at 12.2 afr's at wfo on my 1/8 mile test road but should be real close where I race which is at least 2000 feet lower............I will get ft. shocks next then track time oh, Shiloh's rear shocks plant the rear now like never before............ The NGK #8's look real good now at least to me and the car is pulling hard so time will tell............
