Looks like you are gettijg serious with the build

Good thing about the PTC is that they will work with you to get the converter right. Ive heard real good things about that $450 converter,great price and performance. Plus if you decide on the $850 converter down the road, they will buy the $450 from you to give you credit.
The QA1s are a great choice, its good that you bit the bullet instead of buying single adjustables and then having to spend money on double adjustables down the road.
If you are going to go higher on boost you may want to think about bigger injectors and switching to E85. Also, I dont remember what fuel pump you are running but Im currently running the Magnafuel 4303 and its awesome! It does not even overheat on the street with continous use like my A1000 would.
If you jeed any help with the tuning , just shoot me a message.
Also, if you end up getting a transbrake let me know, I'll send you my blueprints on my homemade bumpbox. I recently tested it and it works very smooth.
