As you know my car is back to standard now, bar Omex, but the difference between mine and Mark's car is the ISCV. It's not really needed as the Omex will cold start etc, but it's not like having an ISCV where it does it mechanically. Tis much better, if I was staying stock I'd have one on mine too, but with ITB's it's not needed.
There's a better technical explaination but I'll leave that for Andy or someone else. lol
