One could argue they have too little traction, not too much horsepower. ;-)

One could argue that the frequency of retinal detachment from the vibration, and from the sudden-onset deceleration from the chutes, means that their current performance level is right at the edge of human tolerance. I'd say that's enough traction.

Are they allowed to use computers to control the clutch slip, or is that all mechanical and/or driver?

The rules limit the clutch engagement system to pneumatic valves, fixed orifices, and mechanical timers. The timers start when the throttle is first opened fully. So, it's all open loop. Of course the system of valves and timers is quite complex, with a dozen or so timers controlling one valve each, and each valve adds more pressure to the throwout bearing. Adjusting the timing and pressure setting for each valve, and adjusting orifice sizes to produce just the right clutch clamping force vs time curve, is where the real tuning magic is. In most teams, all of that hardware is in a locked black breadbox-sized container that only the crew chief has the key for. Other than the tech crew, he's the only one who ever sees what's in there.
