tsp220r 112lsa Idle
 

Click clip of how this cam idles on a cold start. Sounds really healthy until it warms up, then it sounds like a stock cam with a hint of lope. Once warm, if you didn't know it was cammed you would totally miss it. In this video the truck is idling about 950-1000 rpm. Once warm, it ides around 900 which IMO is waaaay too high. What are your thoughts? If you don't have the brakes pushed down pretty hard it lunges forward at stop lights.

Clip taken with longtubes and open corresponding y pipe.

My 4.8 with the same cam lopes pretty good at idle which is 700rpm. Without a higher stall torque converter its going to pull at redlights. The high rpm doesnt help either. Heres a link to what mine sounds like

Dragging this back from the dead. You're not far from us. Bring it by and let us tune it. Idle it back down and it should help those issues!
