The tune with stillen kit with only frozen boost exchanger made 345whp if I remember correctly.
The tune with this air to air kit made 368whp on a conservative tune for lap days. There is more power to be made, but a conservative tune gives piece of mind at the track.
Please note the dyno reads extremely low.

We did run into some issues with the y pipe which is all fixed now. Still trying to figure out where it went wrong with TopGunz. Will update once we figure it out.

Also, for anyone who wants to install fast intention crash bar, it fits!

I'm very happy with the results. And want to thank TopGunz for putting together the kit that makes stillen kit so much more desirable!
