saw the boost gauge go to 11psi, should be at 7psi...Jose? havent even gave it a full throttle romping yet, but im wondering why it peak to 11psi before i let off (might have gone higher)
the wastegate should be plenty big, a ProGate 48mm mated to the PTE88, i have the 7psi wastegate spring and full 2" wastegate tubing to the 4" downpipe.
i have the vaccum line directly from the port off the turbo to the wastegate and then to the BOV. pretty sure i hooked it up right ill have to double check again after work though
Jose do you know the lowerst you can set the boost on a PT88 and the 48mm progate
id hope to have it at 10psi or lower due to my little 42lb injecotrs right now.

I'd double check or change any old vacuum lines. I had pretty much all of mine fail within 2 months of each other. Swapped them for silicone and they worked great. you could also check the waste gate by hooking it up to an air compressor (set around 7-10 psi) and see when it starts to open.
FYI one of the wastegates that I bought was "suppose" to have a 5-7psi spring, which turned out to be a 14-15psi spring. I could have really messed stuff up had I not checked it.
My guess it' something stupid like that, The rest of your set-up is by far more effecient then any of the stuff I had and I never ran into a problem.
Later,
Dave

i have new vacuum lines and one directly from the compressor cover to the wastegate (a short 3" span)
guess ill double check the spring to make sure, not sure if i opened it up to check it, i just assumed that it was the 7psi, cause that was the only one i was missing out of the box.

I must have missed that it was going to be fired up,... so congrats on that.
I'd recheck it to make sure you've got the soft spring in there. They may have goofed on the initial setup of the WG if it shipped with the "soft spring" in it.

plugged in the coil packs in the right ways this time
and she runs pretty good, just a little loud.gonna try some tuning tonight, hope my 42lbers will be enough for a while.

bov sees vacuum and works fine.
tested it out last night it with some full throttle passes, would get to 11-12psi good enough for now, my injectors are runninr 115-130 duty cycle, maf sensor is also pegged.
good enough for 128mph traps, hopefully with a little tweaking with fuel pressure ill be able to hit 130's

still have alot of tunning to do, but it got up to 13:1 at 6k on a few passes, jacked up the fuel pressure to 70psi and got it down to 10:1, only got 4 passes so tuning was limited.
gonna hook up the rising rate regulator and take fuel out accordingly.

What fuel system do you run? Do you have an idea of how much power 12 psi is getting you?

^^^ thats what I'm asking?

im not quite sure why you guys dont understand that, the turbo outlet to the cylinder ports get the same pressure reading.
