More load on the engine most likely. Turbo charged cars love more load on the engine, as you tend to have the engine "outrun" the turbo a little bit in the lower gears.

My first gear feels pathetically weak compared to my 3rd gear, and I have a TODA lightweight flywheel and my car probably doesn't weigh much over 2500lbs. A NA car with the same powerband as the SR puts out in 4th gear would absolutely blast off in 1st gear, but sadly this is not the case. Just one of those quirks.

1st and 2nd gear are night and day compared to 3rd, my car used to pull hard in second and level out in the later gears but when i added a manual boost controller to the mix at 10-12 pounds 3rd gear just pulls so nicely, i cant even make full boost in 1st gear with the boost turned up to around 14. Go figure.

Exactly. Once you get into some of the topend turbos, the boost coming on in 4th and 5th feels like 2nd. With the T25 at stock boost, you're going to be making most of your power through 2nd and 3rd.
