Ok just ran up Ron's R34, mixtures down low were around 14.0's now much better. And i turned on the 02 sensor which i must have left off last time,
Went from 182kw to 205kw with some more timing, tune was limited last time by the stock dump pipe which has been upgraded since.
Went for a drive with Ron before putting on the dyno, theres no hesitation as such but the boost controller does a poor job holding boost and is oscillating as it comes on which is the feeling he is getting.
Smoke test came up fine
