Sprockets and GPS

[gregg1]

COL I had a slight stumble with light thottle in 2nd gear, after I put yoshi slip ons on.I have heard about the gps which has different timing for all gears not just 1-4.I built a box with the different resistor values(switchable) from the gps to the ecu.In 6th gear mode the stumble is gone and In lower gears it is smooth and torguey.5th the pickup in even better.My question is with this mod I have noticed more of a pitting noise from the motor in the lower gears.Is this caused by more fuel due to the 6th gear mapping or the retarded timing not in effect due to the mod regards GREG. <i></i>
