If you want your motor to last then you need a tune!! You can just use someone's map and expect it will yield the same result. The turbo size shouldn't matter that much since boost is boost. How your car react on that boost is the difference so you really need a dyno to tune the ignition. Do you have a wideband? What EMS are you using? If you are brave then you can always make adjustment on the fuel but I wouldn't touch the ignition unless you know what you are doing and have access to a dyno.
Do you have any basic knowledge in tuning? Download the Utec manual and read that thing 10x. Do a lot of reading and as long as you get a good base map then you should be able to at least make minor adjustment on the fuel.
Just an FYI, the heat shield bolt that the turbo intake bracket bolts to is very week. I had a real bad rattle for a month or so and finally took some time to look underneath. The bolt which is welded into the floor of the trunk broke off which caused the heat shield to rattle against the floor of the trunk. I ended up just running a stainless bolt from the trunk down through and it's real solid again.

Ok boys...I'm jumping into the Uprev/Osiris pool late Nov......I want to switch to a EBC from my MBC......What is working best with our kit???? The plan is to run different maps at various boost levels and at least one for race fuel. Thanks.
I use the Blitz SBC i-D Dual Solenoid controller. Others have used the HKS EVC model. All have had good results.

apexi avc-r has rpm dependent boost control which i find works best for this kit since you can set the wastegate to be 99% open in the early rpm range. It made a significant noticeable difference in spool up time and responsiveness
Yes, Daniel had the AVC-R and that helped him hit full boost on 1st gear. How was the install?

sold my APS ST a few months ago for personal reasons. However Just came across BNIB STS for very good money. I already know the opinions of Daniel and Bobby at CIN since they back this turbo kit and i def trust Bobbys opinion. So to the OGs that have had STS installed for a while whats ur thoughts? still happy?
