Hi, I was wondering if I need the egr cut-out on the turbo manifold or not. I have a 2001 cavalier 2.4L. What if I don't have it? Can I do something without the cut-out.
Do I need to change the map sensor to make 8 psi on this engine?
What if I already have it? Is it better to have the egr cut-out??
Can I put the 2 bar map sensor without the s/c reflash. I think I will need a AFPR and FMU if I don't get the reflash? Is that right?
