Credits for year model. Correct me if I'm wrong.

Hi All I am new to HP Tuners. I am looking into buying some credits.

From what I understand.

2 credits for a 01-07 Express 4.8, 5.3, 5.7, 6.0, 8.1 = one model one vehicle one year eg, 2005 5.7 express only
6 credits for a 01-07 Express 4.8, 5.3, 5.7, 6.0, 8.1 = all models one year all 4.8, 5.3, 5.7, 6.0, 8.1 eg, 2003
30 credits for a 01-07 Express 4.8, 5.3, 5.7, 6.0, 8.1 = all models all years from 01 to 07 Express only.

Am i correct or am I missing something.

Thanks

30 credits would get you the unlimited gen 3 truck license which includes alot more than just the 01-07 express ie silverado, sierra, suburban, etc.

2 credits gets you a single vcm license ie one ecm from one vehicle.

Thank you that answers my question and solves my problem.
