I'm looking into getting the Vishnu V400 Power Package, just wondering if anyone has gotten one of these, and how happy they are/were with the results. Three questions I have in particular are, does the Forced Performance Green Turbo have more or less or about the same lag as the factory WRX Turbo? The second is, from the pictures on their site is looks as if they might use Perrin exhaust systems, anybody know if this is true? And the final question is, what is/are the difference(s) between the Standard and Signature exhaust sytems? Any help will be greatly appreciated.

Also, on a side note, what other companies offer power packages in the $4-5K range that offer between 400 and 500 HP? More specifically, I am looking for a package that is prety much like the Vishnu package with an upgraded TMIC and also possibly a fuel rail and maybe an I/C Spray setup. I can piece together whatever I want I suppose, but then my ECU is flashed for all the stuff in the V400 package and I wouldn't be making full use of my other parts.

Thanks
