I have a permanent installed WBO2 AFR gauge on the dash and it's the very best money spent to get one if you don't have one. These AFR gauges give you a clear indicator of how fuel and air are burning in the cylinder and you have an instant visual aid via the gauge.

You need to tell the 911SC guys how you tune the 911 3.2 engines for more torque
by tweaking the timing and AFRs. The 911 3.2 engine is basically a 911SC with a longer
stroke (4mm longer) and basically the same CR. Little to no performance tuning has
been discussed for the 911SC as has been for 911 3.2. Sal, help these guys!
Note: Sal has his own performance chip for 911 3.2s.
