Vmp tune

[melvincarrillo99]

So recently got my vmp tune but the car idles off and dies says there isn’t no codes currently air fuel ratio is 14 vacuum is 13-14 at idle but then the car dies out of no where. I have a cobra jet set up, 47lb injectors, longtubes, pmas and vmp 69 dual throttle body. I know air fuel ratio seems off maybe I need fuel? But the car doesn’t want to move at all stumbles then dies.

Why did you get a vmp tune lmao.

As for your issue you need to check for vacuum leaks. Your car is not getting the maf readings it is expecting and as such the car is having a really hard time running. MAF is probably fine itself, so either there is a leak or the vmp tune is bad.
