Do it now or wait?

I will be adding Hooker headers and power pulleys this time next year. I want to take a short trip to LG Motorsports to Dyno and LS1 edit the car. My question is should I wait to get the headers and power pulleys first? Or will it really matter as far as tuning the CPU with the Edit? I'm just afraid that if I get the edit now that I might have to re edit with the new mods when I get them.
