frequent questions and answers:

MWMods warrants to the consumer that all of our hardware will be free from defects in material and workmanship for a period of a year from date of the original purchase. Before sending a hand-held tuner , we check VIN of a vehicle in order to exclude the possibility of a mistake. If the module works first time , it will work all the time. However, if suddenly stops working, we ask for a video and a photo to make sure that there are no external damage.
No , MWMods hand-held tuner won’t add neither pops nor crackles because it doesn’t disable any engine protection systems. 

There is no need to keep the module plugged in all the time. You can remove the module after ECU upgrade.
