Hi I'm new to tuning, I own a 2003 tahoe 5.3 and I have two questions. First, can I tune with the stock PCM on my truck. Second, does HP tuner Pro come with a few credits when you buy it ?

1. Yes.
2. No, it does not. Credits are still their own cost.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Thanks a lot
