Ian, you seem to have turned a new leaf. Your posts recently have been informative and well written. Keep it up!!

6PSI System
Horsepower: 400 hp
Torque: 413 ft lb
0-60MPH: 5.7 seconds
Install: 12-14 hours
Price: $7995


8PSI System
Horsepower: 422 hp
Torque: 437 ft lb
0-60MPH: 5.2 seconds
Install: 12-14 hours
Price: $9995

You can get more info from here.

However, you should really consider the 4.8is if you're willing to spend so much money on a mod that will void your factory warranty. The 4.8is is almost as fast the 6PSI system-4.4, yet retains the perfect balance of a tuned BMW engine. Oh, and you're covered for 4 years of warranty!
