Would be interesting to see what they can get out of the 250. I had a Stage 3 put into my BMW 135i and it achieved a claimed 390 Hp and 429 lbs ft of torque. I also dumped the secondary cats on my Cayenne Turbo as well as put in a lightweight Fabspeed muffler on the Cayenne and a cat back sans muffler on my 993 Turbo. Marginal gains in Hp but faster spool up on both.
