Hi Guys
today for no reason truck feels slower than normal so i look at my boost gauge and its only at 2 psi max it would not go over that what ever i do....

normally i would see 7 PSI easy, whats weird is the truck starts and drives normal no ses lights or anything that i can point a finger at..i changed the spark plugs and nothing its still the same what else could it be thanks..

any ideas please

Oh its a 2000 5.3 with bolt on's and the Radix

 

How about feel? Does it feel like it is only getting a 1/3 of the boost?

Who installed...yourself or professional?

With my boost/vac tube on my FPR (fuel pressure regulator) unhooked I was getting negative 17 to only positive 2. My max when properly hooked up is 10.6 psi.

So if you feel like it is getting power but you really can't tell, check your vacuum lines. There is obviously a hundred...errr....a thousand things that could be wrong but stick to simple first. How long have you had the radix operational?

 

Have you done any work on the truck lately? If so, what?

 

Could the blow off have stuck partially open?

 

when i get on it its slower than normal ....it idles and drives fine thou i have no leads to go after

Flyer come to think of it i did remove the stock airbox and i installed a mustang cobra cold air aircharger system i dont think it could affect boost??

 

boost will go up slightly with intakes, and down slightly with free flowing exhausts. So that shouldnt be the culprit. since its cold air, I assume the filter part of it is hidden from view from the engine bay...perhaps its being blocked? Road debris/plastic bag, etc is near or on it

 

Doint ANYTHING to the air intake for the blower could very well effect boost.

IMO, remove it and stock your old setup back on and see what happens..

Always look to recent changes you made. If you noticed something wrong after the change then reverse it and see if it fixes the problem.

Also be careful using flexible tubing as this can easily collapse under boost.

 

Todd thats a great idea ill go look at it and shake it a bit


Dewmanshu i installed it my self about a year ago no problems till now

 

Werd!

 

ok, u made it sound like it was a recent install. Yea, id definitly check for any kind of restriction. Clean the filter while youre at it.
