What kind of fuel pressure are you running? What type of pressure regulator?

60lbs

It sounds like you have too much fuel pressure. I think you would want to be around 36-38 with the vac line off at idle. That is what I have always been told and works for me.

 

[turbo nasty]

60lbs

What is your blms at idle?

60 psi is waaaaay high.

What is your voltage the scanmaster reads at idle?

I don't have a scanmaster at the moment using a fuel pressure tester but I think it's broke cause id think is that much fuel now.... Srry guys just need to this n still need to get the right tools for my job... But ik the right tools can y'all help??

But I really don't know was up with this car.... I have a new cam sensor but don't want to waste the time if it's not really that cause I never drove the car that far just start it ride a block n park so idk..
