you all for your help previously. I have this sled back together, but am having a problem with upper RPMs. It has no upper end power. I have cleaned the APV's. When I start the sled, the servo motor cycles once, but when I have it on the stand and got the rpm's up past 6500-7000 rpms With WOT the servo motor never opens the valves. I think that is why I have no power on the upper end, but I don't know how to find out why the servo is not opening the valves, even though at start up it seems to cycle correctly.
Do you have any suggestions?
Thanks
Dave

FOLLOW UP... I pulled the cables of the servo and checked them, they open the valves and snap right back as I think they should. Also, I had both clutched lloked at by the dealer, the secondary was rebuilt and a shim removed, and I was told the primary is great.....
