Can any of the Cali folks help me out?
I have an Sct X3 with Matt's SRL, 8K, and Unlimited tow. Just the basics. Being new to diesels and the X3 I have a couple questions.
1st When I load one of the custom tunes will the X3 automatically save my stock tune? Is there anything I need to do before I load a tune?
2nd I don't have an aftermarket exhaust.....yet!
The mods I do have on the truck are nothing special. You can see in my signature. Truck only has 64k miles on it and runs real strong. So my question is, should I wait to install the exhaust before I run any tunes?
Thanks for any help guys.
