Is LDA pin grind worth it with K03?
#1
Ok I have converted my xsara dt, to bosch few months back. Runs well, about 21 psi max. on a stock K03 and a top mount inter cooler. 

However no matter how I rotate the lda pin I just can seem to find enough range of on-off boost fueling. If it has enough fuel on boost, it blows smoke off boost and in  a weird way somehow bogs down the car low down, slowing spool up (which on the k03 should be pretty much instant).


If I set the lda pin on a less aggressive slope it spools up faster, though feels a bit lean when on boost. 

Pretty much every position of the star wheel has been tried with little change, currently sitting about 7 turns from the bottom up.


Now is lda pin grind even worth it with k03? I understand they are very small turbos and they cant take much psi wise.
