RK Tunes results
Hi... just wanted to share some quick results from the RK Tunes ECU flash. The car is 100% stock, and has around 2,500 miles.
Both results are using Launch Control. With the tuned result, I did experience some tire spin right off the line, so that number may be able to be improved. Stock: Tuned: Using a basic online calculator, that translates to about an 80HP gain (at the flywheel). |

I had planned on the JB4, but then decided I didn't want to have to "install" anything. The Rk Tunes (like many others) is just a flash update via the OBD port. Easy to remove and re-install any time.
I'm sure the JB4 would provide more power, but the ease of install was worth it for me. |
