The red line SB ..the blue OE. If you look at where the red line goes up first and the blue line goes up second (the start)that is where the pedals were FIRST stepped on , the red was stepped on sooner than the blue, that part of the graph is due to the person stepping on the pedal sooner with the SB Than the OE, Now if you over lay the two line so that they have a equal starting point They have a equal curve pretty much until A LITTLE BEFORE 1/2 pedal where they begain to seperate, Now from half throttle to full throttle The red line gets there sooner than the other, This could be good, this could equate to throttle lag but look at the time frame 0,4 (FOUR TENS OF A SECOND) Theres no way you could feel that . But if you notice At 3/4 pedal you max out and the throttle and its all the way open the red one, at full pedal the blue one is there maxed, the both maxed out full open Right, the red one was sooner right, now look at the time it took to do it all, FOUR TENS OF A SECOND, now when you look at the time where the two lines seperate its even a smaller time frame, So the only thing it does THE SB is allows you too use less pedal to Achieve full throttle, WHICH GIVES YOU THAT FEEL...IT DOES NOTHING FOR THROTTLE LAG ...WHICH I AM SAYING AND HAVE BEEN SAYING...IT LETS YOU USE LESS PEDAL THATS ALL IT DOES...
Now im sure the next question is where did you get the graph...from the SB web page
