few questions.
1. why people worry about warranty with flashes? can't you simply revert it back to stock mapping?

2. does ecu flashing have extra equipments installed in your car? if so, can they be easily removed before bringing to dealer?

3. ecu flashing, requires a tuner to perform the task or can be done by yourself. i saw the superchip posts, they talk about plug in to computre to download maps???

4. after ecu flash, does it require a dyno tuning? to tune according to your specs of the car? or is it just a generic flash for all stock cars?
