i was just at the turbo installers, & he told me if i keep driving my car like this, damage will happen. about a year ago i sent my ecm back to get re flashed because of pinging, when i got it back, most ,if not all, was gone. & under full boost my air/fuel gauge was under 12, now it's between 15-17. i only use 94 octane gas here in canada, & i replaced the plugs with no results, also had the fuel system checked(nothing wrong there) what the turbo guy was saying to me, was the possibility of the rain water getting sucked into the cai, which he says will cause havoc. he told me it was very wet, & keeping the car over night to dry.
now, does this make any sense to anyone, & if it does what is everyone else doing about this problem( oh wait, you guys probably don't get liquid sunshine, like we do on the wet coast, i mean west coast) british columbia
aaron@hahn was saying it would most likely not the tune, as it was good before, & those things generally don't change,
any suggestions???????????
Getting the CAI wet could be a big problem. If the filter gets soaked it could collape and the fragments could end up inside the engine, Not to mention what happens when the motor inhales a lot of water.

15-17 Air Fuel Ratio at WOT while in boost? If that is the case I would stay out of boost completely that is really lean. Is the car running rough? Do you know what your fuel pressure is? To jump from 12 AFR to 15-17 something pretty major had to happen. Did you see a decrease or increase in boost pressure? Have you done any other modifications to the engine recently?

If your running 15 to 17 AFR under full boost, park the car and find out what is wrong?????
Your going to fry the engine!!!
What has changed since you were running under 12 AFR's? Did you do any other mods or change anything? If not, check for a fuel restriction somewhere in the system. If you have a Dashhawk check fuel pressure under load and check other obvious readings like temps, pressures, etc.
Good luck,
Frank I

Back in the day, while running Hahn stage II, I put my car on a dyno and the afr spiked to 14+ and the tuner shut the engine down for fear of blowing he engine. We had to back the boost off to around 6.5lbs to get the afr in safe range (around 12/1).
At 15-17 afr shouldn't the car detonate much more than it did before?

no other mods at all, the pinging just seamed to get worse with time. i'm waiting for a call about the rain in the cai. he checked the fuel delivery, & no problem there.
Ok, what boost pressures are you running? The max boost you should be able to safely run on Stage II is about 8psi on 93 octane. Also, check your BOV and make sure that it is functioning correctly. I have hear stories of BOVs going bad and causing havok as there is no air released from the system and it causes an overboost and lean condition.
Good luck.

The wet CAI won't cause this problem. If anything it would cause a rich condition since your not getting air flow through the filter. How does he know the fuel delivery is fine? Do you know how much boost you are getting? DONT DRIVE THE CAR!!! OR BOOM
i just got off the phone to the machanic, he's hasn't taken it fot a test drive yet, but what he thinks so far is that the mass air flow sensor is covered in oil. he mentioned this problem to me back at the beginng of october when he replaced the warped manifold., i think he called it "blow by" or something like this, he told me that this is not normal & i should call hahn, which i did, aaron@hahn told me at that time if i wasn't burning blue, which i was not, then not to worry about it. which now brings me to this date. now, i guess i get to worry about it.
but i don't know for a few more hours yet, & will be calling aaron tommorrow to see what he thinks, i'm not very machanical, so i really don't know what "blow by" really means, all i know is that the machanic says oil is going everywhere, but i'm not burning it.

If you have oil everywhere and it not not caused by bad pvc, then I expect your
lean a/f caused bad detonation which u did not hear or catch and u have broken a piston
ring and are now getting blowby which is excess pressure getting past piston and causing oil to leak into pvc system and also burning in exhaust and when bad causing the
"blue" exhaust. Do a compression test and a leakdown to find problem.
