Hello everybody, i just have a quick question about boost #s. My 01 usually would run between 18-21psi. I removed the box to go to the dealer and now it is acting really wierd. Sometimes it will max out at 12-13psi and other times it will max out around 17-18psi. the weird thing is truck doesn't seem to run any different and my egt's are about the same. Has anyone had a guage go bad?

 

where do you have it tapped into?

 

I have a boost bolt

 

yeah it could be your guage. What kinda guage u got? I also had a buddy that it was doing somethin similar to what yours is doing and his fuel filter had never been changed so he changed the filter and it fixed it. You can try that I not 2 sure if it will work though.

 

yeah I dont think its the filter though cause I change my fuel filter every 10,000 and have only about 2500 since last change
