PTE 5557 Turbo Vs 16G tuning

[5558DSM]

Hello everyone,
Just wondering if anyone has any tuning experience swapping a 16g to a larger turbo such as mine, a 5557 journal bearing. I recently did the swap and am finding that the power difference has me very dissapointed. The 16g was running 22lbs with up to 19 degrees advance at WOT with zero knock. The 5557 cant seem to get any more than about 13 or 14 degrees without knocking and the power difference is a very slight edge for the 5557. I am running 91 pump gas with washer fluid injection. Does this seem normal or is there an aspect of tuning I am ignoring such as needing to up fuel preesure ect. I never changed the tuning much other than timing and afr tuning to keep it around 11.2:1. The only way I have measured difference is 70-90 times which went from 2.9sec to 2.7sec. Any help would be appreciated.

Intake temps?

Log was saying 78 degrees. does that make a big difference?

Same for both turbos?

There are a lot of variables here.

Ya it all depended on how long the car idled while I was checking logs but they were similar.

Post a log. Preferably both 16g and 5557

If fuel ever sat in the tank it could be a little less volatile I guess. My bosses EVO would run like shit on three week old 93oct.
