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.

Using a basic online calculator, that translates to about an 80HP gain (at the flywheel).

What is the significance of 0-60 (1ft) time? Not familiar with this app.

What's your 60-100 time? I'd like to compare it to mine.

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.

i actually dont think it does(I could be wrong) JB4 is cool because you can essentially mess with it after the fact, increase boost, data log it, etc, and stack with a flash.

for a set and it forget it tune, i think any of these obd2 flash are way to go.
