Hi Steve,
When my ed30 was stage 1, the default settings were b6t5f9.
Mine is stage2+ now and running b8t6f6.
Whilst I haven't seen logs for your car, fuel 6 is reasonable, but t4 seems rather low - your signature doesn't suggest you have an uprated intercooler fitted ?
Mine ran perfectly fine all year round with t5 but with the twintercooler I've been running t6 all year without any timing pull.
