thanks bud for the link and i have noticed that the hp and Tq with SMSP and Toda headers are almost same?

I thought that SMSP header was way better than the TODA one? But from the dyno results, it seems that they are very similar.

If Toda header is cheaper at 980 US and has less waiting period to receive, isn't it a better choice, what do you guys think?
