I was aiming for around 9 as well what meth injection kit did you go with?

I had a check engine light as well but it was due to the tune. Once Marc at STS sent me few new tunes the issue was solved but with the shady install of my system I have two exhaust leaks currently. I'm having my new tuner change out the clamps for flange connections and he is also going to move the AFR "sniffer" where it belongs...AFTER THE TURBO. Also gonna push 9-10 psi on the system to see what it can handle (with the meth injection system).

Do you have any pics of your system? what kind you went with?

I think Tower used STS's setup, I chose to go with Snow performance boost cooler 2 setup, I have a few pics on my profile, hope to update with some more. Install was pretty easy, just awaiting a tune to see the true benefit.

Thanks Im looking at Snow also, I'll check your photos out.

That is a nice custom tank you have, what size is it.

Are you gOnna tune it for meth or just use it for safety ?

Thx the tank holds about 5 liters

Probably as a safet, but I was gonna talk to the tuner beforehand to see what he recommends, mark at Sts suggested tuning it without and then using it as a safety.

Yea thats exactly what I was thinkin

K guys so slight hiccup , my car idles high and fluctuates down to 500 rpm but then goes back up to like 1100 or so, my vacuum is also low at idle, this screams vac leak I know any places where I should look first ?

whats your vacuum at?

Like 12 at idle and my bovs don't work while boosting it just all goes out the turbo

A leak for sure, I pull 20 at idle. Your best bet is to do a boost leak test but if you don't have the equipment you need to inspect manually.

Check all the couplers/tbolt clamps, vacuum lines to/from BOV and wastegate, check lines on the intake manifold.

Also I know people have trouble getting a good seal on the intake manifold, spray some carb cleaner around the base of the intake manifold/runners (I know this is difficult to do with our car). If your idle jumps its a leak.

I cleaned my manifold gasket really well and used some spray on RTV to coat the gasket, then I torqued it down in order as per FSM to factory spec, 8 ft/lb, use a torque wrench!

It's an exhaust leak....I know had the same issue. Check the clamps on the piping. When I had it up on the lift ,running, I could fill the air flowing out. My vacuum pressure went from 20 to around 11. Then the other side started leaking and the boost went from 9 to around 6. You can only tighten those so much before they have to be replaced.
