After almost a year of the sixxer being down and out with a destroyed rear end and no inspection/emissions, everything is back in working order. So last Wednesday I took off a day of work to head to SGS Performance in Dillsburg, PA for some dyno-tuning. I had known that the base tune I got from Andy was safe enough to drive around a little with but dynotuning was really essential. Between 2000 and 4000 rpms I was seeing an A/F as low as 9:1 and above 5500 rpms it would go lean. The guys at SGS were awesome and Dave, their SCT tuner, is great at what he does. He fixed my idle immediately and adjusted my A/F to 12:1 all the way up through my cut off at 6200 rpm. From the base tune I gained 37 rwhp and 24 rwtq - up to 375 rwhp / 345 rwtq. :)
