Update!!!
Fixed the boost dive issue. Id run out of gate spring. So i borrowed a kinagawa gate a mate wasn't using and threw the 22psi spring in it and seems much better.
BBBUUUUTTTTT it's now running at 98% duty on the injectors 🙁
Meaning power should be up a fair bit too.
Seeing as dave mentioned economy numbers in his beemer thread i thought I'd crunch some numbers.
So its 1000kg, 45ltr tank, E85 fuel and 5spd.
Last drive was exactly 180km round trip from the mornignton peninsula to yarra junction. Half was freeway the other half stop start and twisty mountain roads, just fiiled to the brim with 16.2ltrs, so bang on 9ltr per 100km.
