I haven`t driven it much, life has been in the way, If I remember right, around 72ish at 3000/3100, my speedometer bounces around about 5 mph. I need to get the engine fully broke in , still don`t know if I can trust it yet, LOL . Still experimenting w/ the tune /what little I`ve messed w/ it. Seems like I need a one step hotter plug. I have a fair reading on # 7 plug, the rest look rich as he--. I did put some seafoam in the last tank of gas, was thinking one of the eight injectors might be plugging up in the throttle body. Seat of the pants feels better. Planning on driving it again today, and prayer breakfast next Sat., if not raining.-------to be continued------
