The cheap route would be to buy a MAP clamp (after you invested in a return line) and tune it with a wideband.
Hope this helps. And like the mod said... Do some research!
18.5 psi, but now we're just splitting hairs
i ran an AGP WGA and mapclamp setup on my stock pcm for a while w/o issue. make sure you get a wideband to monitor AFR and consider a scan gauge to monitor knock.
its good you have the stage 1, that way you wont need the tip mod to keep from popping cel's, since the car is 05
good luck, do your research, and be safe.
