BOOST QUESTION

[mustangfan1990]

I am not sure but I think my boost psi is changing. When I first got it on I was boosting 10 pounds and sometimes it would read 8 now it is only reading 5 pounds. Did I do something wrong or is my gauge messed up. It is a brandnew gauge (autometer ford racing) and all the lines and everything are brand new hoses?

possible a vaccum cap somewhere could have blown off. you could also be boosting the crank case. is the dipstick popping out of it seat?

I dont think so...I will have to check

Make sure your belt is tight and no vacume leaks.

check belt tension first if it continues, run a comp. test
