Do a few runs and see how the FF (wastegate learning value) is learning upwards on each run to achieve your boost target. It should be getting slightly quicker each run.

FF will raise itself, given time, the higher target will increase the offset and resulting final FF.
I also said "IF" throttle closure gets worse, raise FUA (as also advised by Terry previously)

Looks ok, try another psi on target between 4000 and 6000, if throttle closure gets worse, try FUA at 12.

It would be great for 1/4m cars that sit in a queue heating up.
Not sure there is much to be gained if mainly used on the open road/track, a Meth kit would likely be better option for that.

Yes set the duty bias to achieve stable boost. Each car is slightly different so it is something to experiment with.

Throttle closure is just a secondary method of boost, or rather torque, control. It is however not a very smooth way to do it so if you can control the overboost better at low rpm using the wastegate...

Increasing FUA effectively reduces boost feedback to the ECU and also the base fueling, so ideally tune it on map6 for boost but the trade off is the limited fuel supply. I agree the BEF can't come...

EGT available on CAN bus?

It would be great if we could view the exhaust gas temperature :)

It looks like the DME starts to target a richer AFR as EGT rises, with no effect on fuel trims, ie run 1 may be 14.7:1 throughout,...

How does the throttle look on shifts? That's one reason I had to up the FUA. May be ok in the heat but at 0 deg C ambient the turbo is too frisky with no restriction on exhaust.

I would put FUA at 10 to help with throttle closure due to depe then run map3. Ignition advance suggests octane is there to support it.

Is that running on Vpower? Ign timing looks a bit lower than mine but I tip in some NF Octane booster which helps.

A little cooling fan and override on the charge cooler water pump would be a great mod for these cars, they really do heat up the charge when sitting still.

I think you need to be in one of the boost control maps such as 6 or 7 for the BM4 to take control of boost. In there you can set FF and leave it in auto or lock it.

When you think 14.7:1 is lean,...

I don't find the fuel limiter an issue as such, just let the long term fuel trim learn upwards. I got over 440bhp and close to the turbos limits without meth or a flash map. More of a pain is the...

Possibly overboost spike closing throttle, the turbo is much more frisky with the sinful mod, so requires less wastegate duty to achieve target, Try with FUA set to 10 or 20. Can you post a log?
