Are you tuning off the MAP or MAF? Pros and cons of each if you could.

I've got a turbo setup ready to go and I'm wanting to know a little more about tuning and the electronics side of what I need to do. Thank you!!!!

 

MAF tune, the 1bar map sensor wont do you any good in boost, it wont see it...put the MAF in the cold side piping after the intercooler
