Hmm...what next?

[laesala]

Hello all. Been lurking a while, and now I have a few questions that I was hoping someone could answer.

So far I have gapped plugs, a CAI, Intercooler, COBB accessport with the 93 stage 2 map going.

I am a little worried about the amount of boost that I am getting. I am 12.5 psi in 3rd gear, which seems a bit low from what I have read. I recently had a known boost leak that I thought I fixed due to the audible sound disappearing, but am still using the stock clamps, which are apparently very low quality.

However, I have also read that I may need a BOV upgrade to increase boost? Unsure about this....

I was also wondering about the next upgrades to get (besides a custom tune). Originally it was going to be a catch can, but then I read that the 2017 mustang does not need this nearly as much as the previous years. If not that, then perhaps downpipe/exhaust?

Sorry for blasting you all with so many questions!

I was running about 22psi with stock clamps and charge pipes. I am not sure why you are getting 12.5 psi, maybe someone will chime in and tell you. Downpipe/wastegate actuator would be a good next mod.

still have a boost leak for sure would be my guess. there are a couple ways you can make your own boost leak tester. I've seen people smoke cigars and blow into a vacuum line and see where it comes out/if it comes out where it shouldnt be. I've seen a couple people rig up some pvc piping with couplers to the system with an attachment for an air hose. blow air in and listen to where it comes out from. its easy to hear pressure leak when the car isnt on.

maybe this will help. not too sure.

First things first... If you're only seeing 12.5psi you're definitely losing pressure from somewhere. Factory hose clamps are notoriously loose and retightening all of them is recommended. If you wanted to upgrade to a constant tension clamps, Adam sells them on his site for $69.99.

Another possibility is that you're running a Cobb OTS Stage 2 tune, which in my experience lowered my overall boost after I installed my intercooler. You didn't mention which brand you're using, mine is a factory replacement from CP-E.

If you want to address the other possible leak point, look no further than the factory BPV. GFB makes an excellent upgrade that eliminates this from occurring. It's very easy to install and does not require any splicing or other ecu foolery. It's the DV+ and Adam also sells on his site.

The reality is that your best bang for the buck is going to be a custom tune that optimizes your existing set-up and available octane. There's really not much left in terms of hard parts, sure a downpipe will increase efficiency and add a few horsepower, but you would also want to be tuned to prevent over boosting on spool up and other boost creep issues.

I don't think that I would feel satisfied with myself checking for a leak, so it looks like it's time to go to the mechanic after purchasing better clamps. If anything, two of the clamps may be badly positioned. The other four are the ones that came with the COBB kit and a good deal of time was spent to make sure there were no problems with them.

BOV and a custom tune does seem like a good idea. It's a little more appealing at the moment due to being so much cheaper than the downpipe/exhaust.

The CAI and FMIC are both COBB, as I purchased one of their stage packages so that their maps would be most compatible.

To make sure, what exactly is everyone referring to when they talk about boost? Is it peak boost? Taking the highest value after going from standing to flooring it?

Thanks for the pointers

If your charge pipes were loose or misaligned, it would be likely that the hoses would blow off under pressure.
I'm also thinking that that crap BPV might be the culprit.

Before bringing it in, flash back to your stock tune and give it a go, see what your peak boost is.
I had a Cobb stage 2 before I went to Tune +, I would get consistent 21psi.

That was the psi that I was expecting...did you have that before buying a new BOV?

Brooklyn huh? I park a lot around Williamsburg on the weekends haha. I'll keep an eye out for your car ;)

I did a replacement BPV from turbosmart.
And yes, I was getting 21 before the replacement.

Also, I'm in Brighton Beach, if you are ever in the hood......

Well...no one was kidding...just got the tune+ log file and I hit 24 psi easily. Crazy!

First of all, get your boost issue sorted out.. Check all of your hose clamps especially the turbo and the hot side intercooler pipe. If you cannot locate it I would at least uninstall your tune and see if the dealer can nail it down. Don't add power if the cars not running right. Second, if you plan on owning your car for 50k miles or more, I would get a catch can. It's such cheap insurance, and they all work well and yes, all turbo charge direct injection motors can benefit from one.

Once you get the issue sorted out, look into exhaust or a better set of tires in the back to help with your extra power. Once you step up in power, The first couple of gears are a liability when it comes to traction and hooking. Better tires will eliminate that and in turn, turn it into an advantage; not to mention it will grant you a lot more confidence and safety. My 'performance pack' tires might as well have been 225's with how they behaved at low speeds.

Sell the CAI and buy a green filter + Airaid tube combined with the stock airbox. You are giving up power with an aftermarket CAI.

+1 for this comment. I was going to say it but ppl are very sensitive to this subject. addle:

 

[iEcobeast]

But yet some people still buy them for $300+ anyways cuz they like the sound lol.

Why is this? I have the Airraid MXP CAI but always looking for ways to improve

 

[Phil@JDM]

Some CAI kits will increase temps and dont add any power, but not all. As i have stated before, I run the MAP intake on my car and my intake temps are lower than stock and throttle response has improved. Im not saying i gained a bunch of power but i can guarantee that i did not lose any. And on top of that, yes it sounds much better.
