well.. I am definitely a failure to follow the "change one things at a time" procedure.
I redid my charge pipes ( i had shitloads of pinholes in them) and removed the e-bay RFL and went with a dsm gen-1 bov with the boost ref port blocked from boost and vented to atmosphere... I also changed from a wg can bleed back to computer control. Once my trimcal comes in I do not want to use a bleed. All vacume lines have been replaced with new.
the problem is the car pulls fine up to 18/19 psi but on the xway that will drop back to 10 psi after a 3 sec wot run...
troubleshooting done: I tried different size restrictors for the wg can (red/yellow/white, smallest to largest) and the same thing for all of them. I tried adding preload tension to the wg can, and using a spring as well. same thing. I removed the vac line from the wg can completely and it went right up and I was able to use my foot and feather it to hold around 20.
I'm wondering if my wg can solenoid may be faulty? ideas?
Also, question on the DSM bov. I installed it... its working, but when im on the xway and feather the gas and its around 20in vac there is a whistle sound. It almost sounds like a beeping. I thought it was my radio at first. is this typical of the dsm 1g bovs making this sound with the boost ref port mod? It is uncrushed.
this isnt my daily driver, but any assistance would be awsome.
Tonight I'm going to go back to the MBC and try that.
I have not checked for any codes yet.
