Need help fixing boost creep issue

[david200095367]

I have a s14 sr20det with a peakboost top mount mani, t3 t04e turbo, 3in turbo back catless. When i step on it a little not even full throttle my boost jumps up to as much as 26 psi. I dont even push it 100% throttle. I have a 7 psi spring in my tial 38mm wastegate. It is also released to the atmosphere.

Do you have the vacuum lines hooked up?

boost controller hook up backward?

dose it hold boots at full throttle?

[david200095367]

yea i have the side port hooked up to my hotpipe.

i havent tried full throttle because i dont have my tune yet and when i saw partial throttle hit 26psi, i wasnt gonna try it.

hook the vacuum line to the lower part of the wastegate, also thats called boost spike, not creep.

no i think mine is boost creep. Mine doesnt spike up and then settle back to 7psi. it will hold it all the way. Also what do you mean hook the lower part of the wastegate? hook it where?

Let me ask u this question since i dont recall reading it yet..

On ur external wastegate... what size spring do u have..??

Your wastegate feed line... where are u tapping into to get this press source..?? If on the manifold.. why the manifold..?? Why not the compressor / hot pipe..?

When u hit the gas pedal, does it even stop and then slow down to creep to 26 psi, or does it SHOOT straight to 26 psi from 0...?? If its going straight to 26 psi, thats NOT creep... Thats a spike.
