No I never had the car on a dyno.. When I first got the Osiris tune, I had K&N drop-ins and that's all. The high octane map removes the 0-60 full throttle lock-out and I saw a huge difference in performance from just the tune. Later I got a CAI and had it tuned again and felt more gains.
Without a doubt, if I still had the car I would buy the Osiris all over again if I had to.
