Try asking the the "Under the Hood" section. Maybe you will get answers there..

i have my vafc tune at about 13.8/9:1. you dont really want to pass 13.9 as motors tend to go BOOM at 14.2+.

^^^

Every car has a window that it likes to operate in. Most N/A tuners aim for 12.8-13.9 AFR.

You should really consider taking the car to a dyno instead of playing with it yourself.

Id rather pay for tuning than pay for a motor
