Another thing I find I like by having the sprint booster is the effortless acceleration at higher speeds on the highway.
For example you are driving along on the highway with the cruise set at 70mph.
You simply tap the cruise control lever to accel and rapidly hit 80 to 85 in seconds.
It is so damn responsive to a slight touch.
This holds true for just driving along without cruise to.
70 mph give it some throttle and before ya know it your doing 100+
It's great !!
