Default Going lean at 4K WHY???

I upt the boost today after the rebuild as it should now be nicely run in. But had to put it back to 0.6 bar as it goes lean at 4K at any more.
Its odd because the whole rev range is fine apart from at 4k.
From 1-3k the wideband reads 11.8-11.9 at 4k its 13.2 then at 5-8k its back to 11.8-11.9. Ive messed about for ages but can not tune it out. Any ideas?

Sorry forgot that bit, im running the hack with 450 dsm's and a 255 fuel pump. all my setting are at like 34% and they are fine apart from at 4k where it is 29% and still lean. If i add any more fuel it brings the CEL on (map sensor)

its no more than in the USA, infact our killer exchange rate probably means its cheaper to do here

Why, just wait until you can afford to do it right. It's only a matter of time in my opinion........

Because even with the exchange rate then the shipping on a dizzy and then add 30% on that for tax and import duty it gets pretty expensive.
Im also using an BTM to pull the timing that the hack put in.
Am looking at swapping to obd1 with urberdata but have to piece it together slowly.
