Wanting to start making performance mods on my truck and wanted to get your input on here. Thank you in advance for your participation.

 

ive been looking into this...Nelson Performance - Performance without Sacrificing Drivability
it says they will do a tune on pcm and send it to you, you can keep your old one or send it back for a core discount, I need to call them to get more info but anything ive read on them has been good and they have tunes for trucks with no other mods
