Hi everybody. Been a lurker here for a lot of years but finally purchased software and hopefully ready to dive in. I just ordered yesterday so I haven't gotten my software yet so no tune file yet. I do have a question though.
I just added a BTR stage 2 truck cam, heads, newer intake and 60lb injectors to my 2005 Silverado. I had a guy start tuning the truck but it doesn't run well at all(pretty sure the 43lb eBay injectors that are in it right now are a lot to blame for that). But anyway he hasn't gotten back to me which is what made me finally just make this purchase.
My question is, will I need to flash my computer back to stock before trying to tune with my software or can I just hook up and make changes to what is already there?
