well i ordered my parts and a black bear traditional tune Wednesday , I plan on putting my ly6 together not this weekend but the following weekend. ive read on here that the black bear tune can take weeks to get is this true? so my question, is it possible to run the ly6 on the 4.8 tune and injectors as long as I don't do any WOT runs? the weekend of the 20th is the only weekend I have for a while to be able to put this thing together and get it in my truck. a little info on the motor its a ly6 bored .020 over dished pistons 799heads 224 cam headers .I have 40 pounders but I have to wait for the black bear tune so that's my dilemma I have any help will be greatly appreciated thanks
