frequent questions and answers:

Do I get a warranty on a hand-held tuner ?

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.

Will i get pops and crackles?

No , MWMods hand-held tuner won’t add neither pops nor crackles because it doesn’t disable any engine protection systems.  

Do I have to keep the module plugged in after tuning?

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