I really like the standard cam, makes the car really drivable. Chasing power can be expensive, going through a CTS stage 2+ box a year is not cheap servicing which is why I have reduced my power.
The stack dash is great, looks awesome in the car, i've got stack dials in the centre vents as well, the dash itself does rev counter, speedo, oil-pressure, water-temperature, fuel-pressure, voltmeter, oil-temperature, Battery Voltage.
I've also got a Stack dials for air temp, exhaust temp, oil pressure.
And then a colins monitor pro which monitors all the same stuff but reads the data from the data port of the ECU
Guess you could say im paranoid about the engine, but's its well monitored
