Yeh, with regard to my problems (penfold) its definitely only for the first 3-4 minutes if the car has been left for several hours (+6 hours) - other than that it runs really really well. But I haven't installed my PFC yet - just a nismo tuned ECU but like I said I did retard the timing a little but I'm a bit of a newb & was unsure of how this (CAI & backed off timing) would effect things so greatly for that first 3 minutes of drivsing (but idleing is fine). Sorry again for stealing the attention but I though the two seemed related & was looking for answers.
