Guess my dyno was acurate. That's like the third or fourth tuner to say this.

He dynoed another L99 a couple days ago, and I believe it made 316 rwhp. He said it dynoed pretty similar to mine.
Super rich is an understatement. He literally said my car was so rich it was off his a/f chart (couldn't read it).
No, not too concerned with my warranty. I'm also planning on getting long tube headers and high flow cats sometime in the near future. I'll need to go back and get my car re-tuned for that.
I'm telling you if you felt the difference in performance with the increased torque and reduction in torque management you'd be sold on getting your car tuned.
