Alright so I currently have the old injectors out. I'm waiting for the 190/100 to arrive. I was going to order a couple new tunes but forgot to get the strategy numbers and all that before pulling injectors. My question is once i get the engine back together can I run the factory tune or even one of those god awful canned tunes until I get a new one? I have 3 from Eric for stock sticks. Or should I just wait to run the truck until I have the new tune?
