i have having boost problem's ever since i installed the forge wga the car has a lazy spool,but over boost with the boost controller turned all theh way down i get 27 28 pounds then tapering very fast up top to maybe about 19 psi,this is a bran new forge wga,and a bran new boost controller i know it is hard to tell from pics,but is this adjusted wright:














thanks for your help this is driving me crazy

 

nobody?

 

my buddy has a turbo gto and he bought a brand new boost controller and it was defective from the factory....think that might be it??

 

^no because i bypassed the boost controller just to run off of wasgate pressure and it still spikes?

 

Sounds like a vacume problame. Check your lines and make sure there all good.

 

no it is not a vacum problem there is something up with the wga

 

What kind of turbo are you running? How much pre-load is on the wastegate?

 

here's some info that might be interesting to you https://www.evolutionm.net/forums/sh...d.php?t=306176

 

i seen that thread but that dont help me much,they are talking about the two diffrent wga,fp and forge...i hope this thing is not broke all ready i just bought it,but no matter how i adjust it the boost is all over the place..i have no luck with forge products......

 

Did you adjust the actuator rod's length so that it just slips freely on and off the flapper valve's pivot arm?

 

there was a little tension

 

If you want help start by answering my question above.

 

just want to say i bought a bran new for wga from no limit motorsport had it installed by a shop,and the car just overboost no matter what i do,did a million test to the car because i was in denial that a bran new wga could be broke, shure enough it is...called forge today on the phone and they were as rude as could be,told me that something else is def wrong with the car and it cant be the wga........this is not the first time forge stuff broke on my car i had there orginal blow off valve on the car that started leaking,so i replaced it with there new design and that broke to.....so i give up with this company........getting very pissed about to order a 35r with tial everything because they seem like the only company that has a clue........

 

I had the same issues at a Dyno Day this spring. It turned out that there were 2 issues. 1) I had bent valves, screwing with my psi build up, 2) the spring in the wastegate was rated between 21-25 psi.
Other than that, I really havent had any problems out of their parts.

 

are you sure you just dont have too much pre-load on the wastegate?
