i hear all the talk of boost creep, and i had quite alot on my s4 , full exhaust and TID mod, and i was hitting 15 psi,

i heard the s5 turbo and waste gate system produces alot less boost creep, is this true???

im wondering if i should port the waste gate or not?? ive never used the s5 turbo before, so i dont really know how much boost creep occures with this setup...just full3" xhast and tid mod

 

It still creeps, from what I remember of my friends 91 Turbo. It depends on your setup but you should port the hell out of the WG port.

 

unmodified Stock vs stock, I though the S4s never had boost creep problems. My 1991 TII is running 1 - 1.5PSI over stock with downpipe, high-flow exhaust, & catalytic converter. I dare NOT put cold air intake until I get a decent BOV & Pop-off on the car.

 

mine boost 10psi in first 3gears but falls too 6psi above 5500rpm....

4th and 5th it spikes at 15psi and hold for a few seconds then falls back down ( BAD! )....

and in 3rd it spikes at 12psi for a half second then down too 10psi, then 6psi....

check my mods in sig....
