Adding more boost & meth kit, how important is new tuning?
I'm debating changing my pulley for a little more boost and adding a meth kit. I'm already tuned for the 13.5psi I have now with no meth. When adding more boost does the tune need to be changed? I'm adding the meth kit for a little extra insurance. The main reason I'm trying to avoid the tune is that I'm pushing a lot of limits and don't feel very comfortable with the car on the dyno. I would much rather break something at the track going for 9s than on the dyno going for rwhp. I may only get a few passes out of it and I would be really pissed if it broke before I even made it to the track. Any good words of advise on what I should do would be appreciated.

You really should tune to operating conditions. It's hard to guesstimate how your car will respond with more boost and meth without some way to gauge it. Personally, I would tune to your highest operating output and turn down from there. You will probably be fine but it's a lot to risk in case something does go to hell.
