I first put the turbo on, then the SAFC and finally about a week ago, i installed the 450 DSM injectors. Ever since the injectors have been in, my car has been running like ****! I MEAN ****! Now of course i have to tune the afc, but would it be running this bad!? I removed my boost gauge because i got a new pod and a set of autometer gauges, but did not remove the boost gauge line. What really bugs me is that smoke comes out of that line, its really wierd.

 

What injectors were in there when the DSM's were not? Were you also boosting during this period of time? From your timeline, you installed the turbo and SAFC, went and did some driving, then a week later you get around to installing the 450's....is that the case?

Also, what are your settings for the SAFC?

Were these injectors cleaned and flowed before installation?

You are using the resistor box (or individual resistors) for the 450s, correct?

 

have you taken your car to a dyno to have it tuned? When you install a turbo, thre is a need for more fuel, and the upgraded injectors are going to put the same amount of fuel in as your stock injectors unless you upgrade your fuel pump aswell, if you have already done this, maybe your fuel rails are insufficient.

 

well i wouldve gotten a pump, but evryone is telling me that i dont need to change the pump as long as i run single digit boost... im only running around 6 or 7 pounds right now...
