MailOrderTuner is one of the leading LS-based computer tuners in the country! We can custom-tune your PCM based on your modifications and performance goals. We have years of tuning experience on our chassis dyno for proven performance and maximum drive-ability! We tune Gen 3/4 and also Gen 5 LT cars and trucks locally as well as remote tunes. For any custom tuning, you will need to send your PCM to us. In many instances, we will be able to tune and ship your PCM within 1-2 business days that it arrives! You can pay for the tune before hand by ordering here from our site or just give us a call to get your order set up, then mail us your computer with a list of modifications to be tuned for as well as your contact information. If you have a 2005+ vehicle with an automatic transmission you will also need to send the transmission computer module (TCM) to us so we can make any necessary transmission changes. For any vehicles equipped with a 6L80e, the transmission control module is located inside the transmission, tucked in with the valve body. We will need that as well to make any changes to trans tuning. With any of our mail-order tunes, you also receive one free update to your tuning for up to ONE YEAR! Within one calendar year of your original tuning purchase, we will perform any tuning changes for free of charge! All you will have to pay for are the applicable shipping fees! #Mailordertuner #Mailordertune
