so i understand that most people will say to get a tune rather than get a tuner. my question is with the extra power and adding extra mods. do you guys ever throw up a code or chevk engine light. what do you do to clear these codes if you have a mail tune. do you also need a code reader and deleter. also has any like i guess average guy do the custom tuning themselves like Hptuner. like can u just try and figure it out as you go.
