First of all, I would like to thank you all for partitcipating on my issue. It really bothered me since I spent the money and time and I got even worse performance. I worked on every possible issues, and last night I looked at one of the thread about DV relo. Here is the picture.

and here is the DV relo picture from Tcarbon

If you observe careful enough, you will notice that in the Tcarbon picture, the DV is installed side way. And of course, it was exactly how I did mine. After I re-installed the DV, It works FINE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thus, The Tcarbon FMIC kit has no problem. And it certainly increased my car performance. Sorry about giving Tcarbon a bad name, I hope I don't get sue for that
