Uppipe is stock. Fuel filter is going to be replaced tomorrow as soon as I get the part.

ok, well it has to do with fuel or spark then most likely, turbo could be bad too, lots of variables, with out a wideband and computer on the car its hard to diagnose and if its something that only happens so often.

Sounds like a classic boost leak issue.. Look for wet spots around the throttle body and intercooler hoses. Do a boost leak check if you can make the tool or borrow one.

MODS:

lnvidia Catted Dp
3" Exhaust to Aero turbine muffler
Cobb SF intake w/box
5 point grounding kit from paranoid fabrication
Walbro fuel pump installed
ENGINE HEALTH:
New spark plugs
oil changed 2 days ago and every 3200 miles
All aspects of 60k mile tune up done except fuel filter
Injector cleaner used from time to time
NO CEL's !
Compression and Leak down test Showed 130 all the way around on a cold engine w/3% leak down.
Coil packs look good

PROBLEM :
When I get on in 3rd at high RPM's around 5k the car suddenly sputters a bit almost feeling like what Valet mode does if you've ever tried that. This does not happen all the time and has only happened 3-4 times.
I'm told by an Etuner the car is misfiring at low RPM's and not making power like it should. But l cant diagnose much without Codes.
Valve Clearance was checked and they are good.

Car smells a bit of gas from the exhaust is my last thing to say.. Injectors maybe or fuel filter are all I can think of. But again no codes here and I'm going off the few sudden lurches l've had and what this tuner said. Any experience here is appreciated.

Vaccum and pressure tests have checked out. I hit 15.8 psi the other night which from what I've read is peak boost for the cobb stage 2 map. Still at a loss... thanks for the responses so far gang! Keep the ideas coming!

Did you check for boost leaks with a proper pressure test or at least go and check all hoses and clamps?

Just because it makes the proper boost means nothing in terms of a leak or not. A leak after the turbo will cause the system to go rich and will cause excessive intake temps.

Other possible issues are MAF, fuel pressure issues, wrong gap on plugs or weak ignition system. The list kind goes from there. We see dozens of these cars in the shop and 90% of the time they have boost leaks. The cobb tunes are simple and conservative. If your not running right on a cobb tune with the specific ok mods then its going to be something fairly basic.

Can you send me a screen shot of your learned fuel trims and knock values. You can down load racetuner from cobb to do this.

I dont feel a leak in the downpipe coming off the turbo when I have somebody rev the engine a bit.. thw spark plugs are brand new factory plugs gapped at .03 I believe. Should I regap them to .028 or .025??
I had a shop, fw motorsports, check for boost leaks. I assume they used the proper tool for such... I will send you the photo tonight after work for some further feedback. Maybe I can send a data log as well.

Your gap is ok for what you are running.

The downpipe plays no role here unless it or the exhaust is blocked.

Being a shop owner myself I have to ask, what did the shop you took it to think the problem is?

I think its fairly safe to assume this is not a tuning issue as well if you are using off the shelf cobb maps.

Take a look at your AP and tell me what the dynamic advance multiplier is at if you have not reset the ecu.

Well that is good. If it was knocking bad enough or had more severe issues that number would start to drop. On the happy scale your a 10 out of 10. I will also see this number drop when boost leaks of significant amounts are present.

So that still leaves some issues. As already stated by Gabe here you need to get more tools, a wide band gauge is going to help a lot to show us how fuel is going once you WOT. Without that tool you have no idea what your AFR is at. Your logs using the AP will not give you readings that can be used really.

Honestly I think your best bet will be to get to a shop that knows these cars well and spend a few bucks to have them check it out. I'm sure eventually you can figure this out but in depth diagnostics can take a while and not having the tools you need and the experience will cost you in time which for most people still equals money.

So when are you going to bring that fancy car you have to our dyno. I'm still waiting to see a Subaru break 400whp.

Jarred from pdx tuning once told me when I asked him that, on the same dyno whether in 2wd or awd your not gonna see a very big difference in the numbers.
With that said granny, and I'm sure you've searched this, your not normally going to see the same numbers on two different dyno's in two different areas in the state or city, the dyno at Underground is a Dynojet where as I believe the one that P3 has is a Mustang? (Seth please correct me on the dyno you have if I'm wrong) it also depends on what correction factor is being used, granny there are alot of variables to account for.
Honestly the dyno is just a tool being used, best way to judge increases really is get a baseline number after 3 pulls and then do it again after all mods and tune are completed and see what kind of percentage of gain has really been made.

yup yup, air temp, calibrations, manufacture, all these have a play in the number put out. like tribal said stick with one dyno to see if your mods are making progress. if you want to see if your car is more powerful than anothers (which doesnt mean your faster) take both cars to the same dyno on the same day. the best use the tool is the engine break capabilities. it allows you to tune aspects of the engine that happen in split seconds of road tuning.

Totally understand that no dyno reads the same. That's why I said I was curious to see the difference by having a car that's been on Nick's go on Seth's. I also have no interest in trying to say I have more power than someone else. I have a number that I would like to get because it is my "safe number" that I know my motor can handle. A dyno would simply show me that I'm still safely in my limits.

Our dyno at P3 Import Autowerks is a Mustang dyno. It has been fully calibrated and certified. Mustang dynos are known as the "heart breakers" in the industry and tend to read much lower than other dynos. There are also different methods used to measure power output depending on the dyno used.

Our dyno is fitted with the latest technology and is capable of self calibration and correction factors based on a ton of factors including what it reads at its weather station. Before each car is tested we also run thru a parasitic loss calibration for each car to make the numbers even more accurate. Once we have the system calibrated for the specific car we can then save those settings in the system for the next time it is tested. These kind of profiles allow us to measure drive line losses as well and can help use detect issues with transmission or drive line losses that are excessive.

Our setup can be run as AWD linked, 2WD linked or unlinked.

As stated here I would not get hung up on numbers from one dyno to another. On a side note it is also quite easy for a shop to manipulate results as well. Whats important is a solid base line of your car before mods and then readings after mods and tuning.

One final thing to consider is that although it is possible to simulate proper road conditions on a dyno, the reality is that its not economical. For instance we use very large high volume fans to attempt to provide air flow to cool the engine, intake, intercoolers, etc. However it would take an even more significant amount of equipment and investment to be able to provide the kind of air flow your car would experience at say 45mph or more. So this means intake temps alone can be a good deal higher then they would be out on the road. I'm sure every turbo car owner here can notice the difference in the seat when it comes to hot weather vs cold weather and what a difference it can make. I have seen almost 100whp difference so far in a car from the first run to the run where we knew heat soak was taking over. In some theory a car that reads say 400whp may be closer to 450whp or more when out on the road with proper cooling and conditions.

I can run you thru tests to show your WHP and estimated crank power as well by measuring your drive line losses.

I need to book some rent time with him in Mid-May depending on availability. You should hit me up and come with your car if time and your budget permit around then.

Sounds good. I'll need to see if I'm fishing then or not.
