problem is fixed, the sled left my shop tuned for the stock exhaust can modified to my specs and a stock 05 rear suspension, chris put on a gp-1 exhaust and a wahl rear suspension, nice pieces, but the exhaust requires jetting changes, and who knows what the clutching will need for the susp change, one needle clip and two main jet sizes richer, and it is running like a champ, made 212 hp on 8 lbs low boost, and 250 hp on 12 pounds hi boost, installing some guages on it for chris now, and we will tune the clutching for his 136 long track. set-up is everything, if you change things, you can't expect things to work the same. its too bad my kits rep had to suffer. jeff
