Has anyone in here ever added a cam to their 392? I had a Stage 1 added to my Scat Pack and, at it's core, it's a cam and ported heads. The engine is now topping out at 600hp which is SO MUCH fun to drive but... I'm now experiencing engine surge while at idle. Sometimes it's so annoying that I put the car into neutral until the traffic light turns green.
The shop that did the work has been fine tuning the car since Day 1 so it's gotten better than it was on the day I got the car back but still... the issue persists. They keep tweaking the air flow at idle but, anyone have any other suggestions?
I keep suggesting a torque converter with something like a 2,600 rpm rating. That would stop the surge power from the engine reaching the transmission and thus would quit tugging on the breaks, at least that's my thinking. It would also help me off the line and reduce 0-60 times, an added benefit. But, am I thinking along the right lines to reduce the jerking and tugging while at idle in drive?
I have attached my current tune and a couple test drives I did in both Sport and Normal modes. Any help would be greatly appreciated.
