Checking for boost leak?

I am running COBB stage 2+FMIC and I have had some boost leak issues. A little while back I had all the fittings to the FMIC tightened and the P3OFF boost leak code didnt come back for a while. THen it happened 2 or 3 other times but all spread out. I just had the P3OFF code again the other day. So Im starting to think there is definately a leak somewhere. Is there some kind of test to check for boost leak? Or how is it found? I am about 15-20 minutes north of philly, does anyone in the area have a test for boost leak?

I don't know how you would go about testing, but do you still have the OEM charge pipe + DVs?? It's possible that with the significant increase in boost (stock is ~9 psi, Stage 2+FMIC peaks at 19 psi) that you've cracked the OEM CP or the DVs are leaking (both those pieces are made from plastic).

Yes they are still stock. So Im wondering if it has anything to do with that? I was thinking of getting a different charge pipe because Ill be getting a meth kit and will need a new charge pipe. Do you think that could solve the issue?

I would try to get a compression test ..but that wont tell you where the boost leak is.

other option is a smoke test, not sure who does it around our area though

If the CP is cracked then obviously replacing it will fix the problem (you'll be able to look at it when it comes out + see if there's a crack). But it's just as common that people's DVs leak from being overstressed -- so you might be best off upgrading to an ER charge pipe + Forge DVs/a BOV setup to guarantee that there won't be any more leaking.

I know it's not exactly the most cost effective solution, but it'll guarantee that you have zero leak issues once both parts are upgraded.

Just a dumb question, do you have a ROM version other than IJE0S or I8A0S?

i had a massive boost leak from the brake booster vacuum hose that refuses to throw any codes. it's also connected to vacuum lines that control the wastegate position.

just get a smoke test done. otherwise, you're going to go crazy hunting down a leak and replacing lines that are fine.

Yeah I havent heard of anyone doing it in our area. Looks like Im going to have to get on the horn and start finding some places...Not ideal because you never know what kind of shop you might run into. Im hoping HELIX does it. But Im not so sure.

Nope that's a good ver. If u had an older rom version they'd trigger boost leak codes with no boost leak.

I don't know if VAC has a smoke machine, which would be used to diagnose a boost leak, but they can almost definitely find a boost leak for you... And probably fix the problem. If you're only 30 minutes from them, you should definitely start with them!

Yeah Im not too far from VAC. Ive had some stuff don there and they do awsome work. I guess I better check to see if they have a smoke machine.

Didnt go yet, not until the 16th. Sounds promising though. I wish I could have went to HELIX or VAC for all of this. But Akuma has the access tuner software and I want the new pro tune put on my COBB AP. I dont think that can happen if someone tunes the car without the access tuner. But we will see how it all goes. Ill keep you informed.

If you want custom COBB ATP maps, you gotta go to an authorized ATP tuning facility:

There isn't one in PA, but there is 1 in NJ, 1 in NY & 2 in China

Going through the p30ff issue right now too. Smoke test done and nothing, so narrowed it down to the solenoids. Car boosts ups to 15-16 psi but doesn't hold... Everyone says they are a pain to change, is this true? haven't seen any DIY's yet.
