I have a 2003 Silverado 4.8, and I recently sent back my intake and exchanged for the intune and wanted to know if its a good programmer and if there were any tips on these things and settings I might want to change to protect the drive train and also i heard these things were known to freeze up and erase the stock tunes and if I should send it back and just get a volant intake and be done with it

 

Bump.
