Did you feel a noticeable improvement in each higher setting? Any issues (CEL, Drive Train Failure, loss of gas mileage, etc.)
Yep, 7 if the highest setting for everyone and 8 is the lowest setting.
Now you make me want to bump it up higher.
So far, a decent bump in torque and HP with about a 2-3 less mpg in similar driving style. Went from about 24mpg down to around 21mpg. Worth it to me - maybe not if someone is much more concerned about getting the highest mpg.
With the bump in performance, it is making my urge to get a 550ix as soon as possible, subside a bit. So for me, it was worth the price of the RC. With the ease of install/de-install on my motor and the bump in performance, if I had to do it all over again, I wouldn't hesitate.
I also wouldn't hesitate to recommend the aFe Scorcher to someone either. Also really easy to install with a nice bump in torque and HP and gas mileage seemed to stay the same.
Once the weather gets better, I'll get a chance to play more and update this thread.
Have a great weekend my friends!
