That's exactly it!! I removed my hoses and replaced them without check valves for both clutch and brake. I havent taken my car out again yet because the calipers wont be here until lunch time, but i am positive that is what is wrong. I did replace them, but still havent gotten the chance to test them.

I replaced the two hoses without check valves at the same time i put in my boost gauge too so thats why i thought that was it. I replced alot of vac lines at the time as well.

Alright I'm going to try these ideas out today and see what happens. I'll let everyone know tonight. Thanks for the info everyone.

[Hi-Rev]

Still no solution yet. I tried resetting the ecu and went back over all vaccum lines. What line exactly is for the clutch and brake booster? I don't think I messed with those. This is exactly what I did: First tapped into y pipe for boost controller. Then I put a t on the other side of mbc and ran equal length hoses to the wastegate actuator nipples. The front turbo wastegate had a short hose that fed to another nipple right near it. I did away with that line and plugged the nipple the actuator fed into. On the rear side I plugged two things. One was a nipple that use to have a white striped vaccum hose and the other was just a nipple down in there that came off the old h connector as well. Also made sure the lines to the wastegates were equal length. This totally bypassed the boost solenoid which was unplugged. For the gauge I simply tapped into nipple behind throttle body with a t and ran one side to old spot beside throttle body and the other to the gauge. Is this right? I know the setup is right but did I plug up something I should'nt have? Well anyways sorry for the long post but I just don't know what the beep could be if I did this right. Next things will be unhook boost gauge to see if it still does it, hook up a friend's datalogger, and recheck all vaccum/boost connections for leaks.

yes..need to start datalogging asap

[Hi-Rev]

Ok well for another time I went back over all major connections except a few hard to reach ones and made perfectly sure they were not leaking or anything. I will check the other few shortly. So far no beeeeeep anymore. Also went ahead and turned my boost down now to 12 psi. I'm just going to leave it there until I can datalog in a week or so to see if I knock at all. I do know I hit 15 psi and held it until i got up in the rpm's with stock 93 octane fuel setup. Just had plugs and wires put on though. No blowout or fuel cut, but until I monitor for knock I will keep it daily driven at 12 psi. Vaccum is a little different than most peoples I think b/c at idle my car is at 14 on the vaccum side. However after reving slightly and letting off it will jump shortly to 18 then back to 14. Is this ok? Another thing is my boost gauge always reads 1.5 psi when off. Is this ok or could it be malfunctioning? It works great but that just seemed odd to me. Hopefully someone can reassure me on theses things. Any advice would be helpful. Thanks.

anyone?

Then it read 15hg. I took it apart and fixed it. So yeah its broken. My lack of check valves are what was causing my beep. i fixed it now.

[Hi-Rev]

Ok I was hoping it might just be that that was just its resting point but be accurate anyway. The guy I bought it from said it was like that when it was new. If the gauge is off +1.5 then could I just compensate and set boost at 12.5 to get 14 or not? Probably not safe. So how did you fix it when you took it apart? What exactly did you do and how hard is it?

Well it requires that you break it and then glue it back together. I pryed off the metal lip all the way around the glass, then the glass just fell off exposing the needle. I twiste the needle which bent the windings inside until it stayed at zero. Then i glues the glass back over the front of it with super glue and thats it. You can't put the metal ring back on, and you will prob get some super glue on the glass.

[Hi-Rev]

Ok. Too bad the metal ring won't go back on. Maybe I can rig up something to hold it on. Thanks for the info. I'll probably be doing this very soon.
