I am about to purchase the MPVI2 with Pro-Features and a PCM Modification for my 2015 Challenger 5.7L. I am totally new to tuning (As in I know nothing about it but plan to learn) and I have researched DiabloSport and HP Tuners. HP Tuners has way more options and customization from my understanding which is great. My questions are:
1) Will I be able to get the car dyno tuned at a shop and later modify that tune if needed? I know HPT seems to have a certain file type they use and wasn't sure if that would cause issues.
2) What are credits? I've read up a bit on them and not quite sure I still understand them. Will I need to buy them every time I wish to edit my tune or dyno tune?
3) If I choose to can I have a tune emailed to me from HemiFever and use that? (HemiFever was just an example I'm not sure if they are DS only or not.)
4) Last but not least does anyone have any tips/tricks or advice I should know before I dive head first into this?
I appreciate any and all help. Thank you.
