What RPM's do you get at idle?

My GTS idles at 600rpm, seems low to me?

That's a bit low. IIRC, idle speed should be around 740 RPMs (+/- 40).

However, all you have to go on is what the tach reports and it can be inaccurate.

An OBD2 code reader/data viewer would let you look at the ECU RPMs number. It would be interesting to know what this reading/value is and does it agree with the tach.

Thanks, with the OPC in the next few weeks so will get them to check over.

My 996 Turbo idles about 800-900 when fully warm.

Cold start can be about 1100 for a few mins.

Idle speed from a cold start agrees with my experience with my stock 03 Turbo with a 6-speed, but the hot idle speed is high. If you are going by the tach the tach is probably reading optimistic.
