Re: not hitting full boost
where do you have the wg signal line hooked up to? the intake mani or the turbo?

Re: not hitting full boost
stock exhaust will be a problem,
especcially if your aiming for 10psi on stock exhaust the WG really wouldn't matter where its set to,(mani or compressor) it should still hit the 10psi spring mark, have you looked at the color of the spring? to make sure its set at 10psi? does the WG open @ 8psi? <-that would tell you alot of things |

Re: not hitting full boost
my wastegate is hooked up to an intake manifold vacuum source. and it will only boost 8psi. gonna put on 2.5 exhaust on with the current magnaflow muffler. the spring is yellow(big yellow) which is rated for 10.??? psi. my old spring was a small green which was rated at 7.??? psi but was only boosting 5psi. so im thinking about pairing the 2 springs to get a rating of 17 psi so ill hit about 12 to 13psi. what u guys think?

Re: not hitting full boost
I would go for a rip with an open down pipe to see if the exhaust was actually causing any problems.
As for the springs, why dont you just hook up an mbc? |
Re: not hitting full boost
so with a mbc i can up the boost passed the wastegate spring psi of 10psi??? i always thought the mbc could only go as high as the spring setup on the wastegate.

Re: not hitting full boost
dude, get an MBC. The 2psi you are missing could be any number of things. This is HMT. If you are missing 2psi, bump it up 2psi. your gauge could also be off by 2psi.
