Can't say enough about how great this product is.

As far as raising RPM limit, I was very surprised to learn that running stock, I had reached 8650+ RPM (per Mike's freeze frame data), so I figured if that happens, why not just keep the rev limit raised!
Thanks Mark for your feedback.

We greatly appreciate the time you've put into logging the car and sending us results to perfect Stage I on 91 octane gas in Norcal. Our customers working closely with us always helps tailor and deliver the best product to end users. We've been fortunate to work with many great people and shops that provide positive feedback loops to ensure that everything is on point.

The car ran solid runs12.9@110 & 13.0 @109 on a very neglected and slippery track

And a pic of the BPM ///M cooling down for another run.
Nice run! Can't wait to take mine to the strip
