It took about 5 minutes to save the factory tune and load the street 87 tune. Then I took the Mustang out for a test ride on my 10 mile test route.
I noticed right away that the slight hesitation when I hit the gas was gone. When taking off from the stop the car just jumps. Then when pulling out on to a 55 mph road and really getting my foot into the pedal the car really popped and ran.
I only had one area to get into the gas from a standing start but this first impression is very good.
Looking forward to a little road trip this weekend.
