Great work! Finally! I bet it feels good to finally have a proper tune! Congrats.
Don't worry about the drop in boost, mine tanks the same way...drops from 37-29psi for me, so your drop isn't so bad, lol.
I'd blame the spool on the tubular, but honestly I bet you made an extra 15+whp from it. Worth it if you ask me
Now time to stop spending money, paying off debt and enjoy the car...welcome to my world if you weren't here already
