They last to low 12s then the usual is a 2-3 flair at 12 flat. You've got time. It's going to take some seat time and tuning before your at that point. Go for a 2800 stall lu converter when it's time to beef up the trans. Don't forget a trans cooler too. Holding boost at the line creates heat. You'll also need some MT drag radials. I'd go with 235s or 255s until you're trapping in the 112 range.
