Performance chip: Suzuki 2009 Grand Vitara V6

[pascal51]

Hello everyone, I have just bought a 2009 Suzuki Grand Vitara V6. Can anyone suggest a performance chip (or other upgrade) that will
1)- decrease the lag time when you press the gas pedal
and 2)- increase gas mileage (if at all possible).
I have seen these on e-bay, does anyone have experience with this? Thanks!

It is little more than a piggy back device. I would steer clear. Have a chat with an OBDII tuning specialist and get a custom remap done to your car. Have you done any other mods to your car? With a proper remap you will only be looking at 10-15% of a power increase.
