i put my stage 4 chip in and i am only getting a boost spike of 15 psi then is settles around 10-11. i dont know what i should look for or should try to get this to put out the right psi.
When I was only seeing around 17psi from my JSP stage 4 tune all it took was cleaning the BPC a few times with WD40, that got me seeing 25-27psi peak, settling back down to around 23-25psi.
Give it a try - spray WD40 in the ports of the BPC, let it soak in a bit, then drain it. Repeat that a few times and it should be nice and clean. Then shoot a low pressure blast of air at the holes (I wouldn't use more than 10-20psi from my air compressor for fear of breaking the brass disk in the BPC valve).
no i didnt have the mbc on the car when i put in the chip, the car has had super in it since i have been driving it, and when i put chip in i put in a new set of NGKs. but i will try the bpc
YUP!!! check vac. lines, wastegate might be fluttering, and check the BOV it might be opening if you have the lighter spring in it. Unless you have the stock recirculating one.
What spring do you have in it? I have the second heaviest in my Forge 001 and mine starts to blow open around 25 psi...when I had the lighter spings in there I couldn't get more than 20 psi.
Clean the BPC again. I did it at least twice, maybe 3 times before it really got cleaned out.
You want the piston/spring/face/etc in the valve perpendicular to the cold side intercooler pipe. In a 9k, facing up. NG900/9-3/9-5 facing toward the driver's side of the car.
So if the valve was transparent the actual piston would look as though it would slide through the nipple allocation in the cold side charge pipe if all other materials of the valve were dissolved away?
This is a little confusing depending on which way the valve is mounted. I mean I could mount it a couple ways and consider it perpendicular to the pipe and simply twist the unit 90 degrees past one of those ways and consider it parallel.
I'm looking for a pic to clear all doubt.
I know this is a 9k engine bay, but it should give you an idea...same principle applies. See how the vac line is facing up? Usually it faces toward the front of the car.
