Well first off, that's a GTS, it's got about 10-15whp more then your GT, so at the most, with his exact mods, you can *pray* for about 215-225whp. The GTS is built a bit better for N/A and tunes as well, with it's fancy-shmancy, better air system. However, if you REALLY read that thread you pulled it out of, you should expect about 185-205whp like the majority of GT owners in N/A.
