25psi Wastegate on 30psi
25psi Wastegate on 30psi
I am having the worst problems in controlling boost. Who all is running 30-32psi spike with the FP 25psi Wastegate? What boost controller are you using? I may borrow a MBC to see if my over boosting is because of the EBC. I have minimal preload on the 25psi and still spiking 35psi with my EBC set to 30psi. wtf... Is anyone having problems running the 25psi wastegate and maintaining a 30-32psi spike?

Blackster: To rule out the boost controller...eliminate it from the loop temporarily . I mean disconnect it for test purposes(Don´t toss it in the trash just yet 
!).
Run a length of rubber hose directly from the WGA nipple to the nipple on the compressor housing discharge tube. Turn the WG actuator rod out to its loosest setting(Loosen it to where it just slides on and off the pivot arm on the flapper valve.)
Essentially you´ll be starting off at base WG pressure. I guess that base on your setup will be around 22-25# due to the 25# actuator. Regardless, though, note the PSI indicated on your boost gauge at the loosest actuator rod setting. Now, shorten the actuator rod by rotating it one full turn and then retesting(You know the drill.). Do it over and over and retest the boost in 4th gear each time.
Thus, testing with the EBC out of the loop you can eliminate or confirm it as a potential cause of your problem. PM me if need be as I am old and have nothing else to do with my retirement time.

It´ll be a little different now with the Red vs. the stock IX turbo. Both use the 10.5 turbine housing, however due to larger turbine wheel on the red stuffed into the same dinky housing, turbine inlet pressures between the IX turbo and the Red are bound to be way different.
Higher turbine inlet pressure on the Red results in higher seat pressure at the flapper valve. This higher seat pressure causes the flapper to crack earlier and lift off its seat more noticeably at the relatively low preload levels that you say you are running.
This peculiar pressure fluctuation dynamic may be fooling your EBC if you think about it. I´d like to explain more how your EBC might be getting fooled, but I am being kicked off my computer at home.

^ I have never had a Hallman, how do they hold boost out the top compared to a EBC? I know with my turbosmart and forge It dropped off 3psi more than the EBC did. I will be going Hallman Pro RX I believe

The Pro Rx?
how much preload do you have?
How many lbs are you spiking?
What turbo?
I started with maximum preload. I've not gotten around to trying lesser amounts of preload yet...
I was describing a RED, just as you were.
EBC's are more complicated to setup but I wouldnt give up on it yet. Just follow the instructions and you should be good. I have used all the EBC's and have no issues. Even the ultra complicated Apexi AVC-R and I have gotten them all to work great just by doing what the manual told me to do. If you want to sell your junk HKS cheap let me know.
