I dont think the cause has really been discussed much...I know Cobb is working very hard on the fix and actually mentioned on a recent post that I think they got it fixed (in v400) and ready for beta release..I havent seen the timing jump that you saw during the hesitation so maybe I need to log a bit more and see if I get the same..(Although im running Stage 2+FMIC ST)

Mine is not exclusive to 3rd gear...but I agree I notice it more in the 3rd gear

Apart from the smoke coming from the exhaust and the f@&$ing wastegate rattle that is... Lol
I tried a fresh install a few days back but no love on the surge/hesistation fix...maybe my issue is bc 6MT no clue..anxiously waiting

Are your turbo on their way out? Still under warranty?......(Pause)....Vishnu Single Turbo......? Haha
