99 GSR Drag Turbo

I installed a brand new 38mm Tial, but changed the spring to the red...boosting 7psi...
As soon as I hit 6000+rpm my car seems to just die down....and the wastegate opens up real loud....


Does it Matter how the spring is installed..could it be upside down? and could that be the reason....?

 

what sort of fuel management are you running?

if its the fmu i would expect that to happen. because you are running more boost, the fmu is gonna dump even more fuel casuing the motor to bog and lose power


how are the vacuum lines hooked up to the wastegate?

 

im just using a the vortech fmu and b&m regulator...

What i did wast just replace my 35mm with a new 38mm and put the old spring in the 38mm.. i never had any other problems...

 

maybe cuz the red spring is only 5.8 lbs and not 7

 

oopps forgot to add..that im using a Profec B boost controller

 

do you know if you're hitting full boost ?

 

yea..im hitting 7psi exactly on my gauge....

 

Is there a possiblity that the rubber skirt is pinched?
