Gonna be doing an lq4 swap into my 04 1500 Sierra In the next couple days. My question is, will my truck start and run without the tune? I'm gonna be in touch with a tuner to get a mail order in the way, but I expect to have the motor in before it gets here, plus I'm gonna have to track someone down to do the crank relearn. Also, are there any other things I need to pick up other than the engine it's self? Thanks in advance!!
