single muffler exhaust See the Gibson Mustang EcoBoost catback exhaust. Late Model Restoration sells it. There's also a sound clip of it on U-tube. It's a single muffler mounted where the factory resonator was, followed by an x-pipe (why I don't know)and going into dual back straight pipes...

Mishimoto intercooler - HP and lost boost I bought and installed the Mishimoto intercooler about a week ago on my stock EcoBoost. I got in on the 40% off 24 hour sale. A K & N filter, the Mishimoto intercooler and a Mishimoto oil separator kit are the only non factory parts on the car at this...

Roush Flash Pack With the Flash Pack at $399 and if the dealer install is reasonably priced, say $75, it wouldn't be such a bad deal and like I said I'd be running the car on 91 octane all the time anyway. That's competitive with other tunes, but you're right, I wouldn't get all the benefits...

Roush Flash Packs I looked on the Roush Performance Parts web page and found this. To find out more, go to their website. Roush EcoBoost Flash Pack ($399) "Calibration is flashed using free Rousch RDT software using industry standard J2534 interface tools. Calibration is for 91 octane...

focus ST According to Autoweek, "the (Focus) twin-scroll turbo 2.3-liter EcoBoost makes 350 hp". That's 350 at the flywheel. Given the weight advantage of the Focus RS, it should kick a stock EcoBoost Mustang's ass unless that EcoBoost Mustang has a really good tune and the usual bolt ons.

ford options I've heard about a Ford free tune update also. But when I asked my dealer about it and they didn't know anything about it and gave me one of those "yea right, dream on" looks. Would be sweet though if manufacturers would simply issue updated tunes for vehicles to improve hp and...

Roush tune I'm not necessarily saying the Roush tune itself is a joke. It might be a very good, safe tune. I would guess that Roush could get enough internal information through Ford to make up a safe tune, along with the knowledge of their own technicians. The reported increases in HP and...

home built exhaust Thanks Dave. Your setup is a lot cheaper than paying Magnaflow $1099 for their street catback. I wonder if you'd have put the Flowmaster Y pipe on it if it would have lined up better

Ford Warrantied tune I can't help but think that if Ford puts out a tune they'll warranty for 3yrs, 36,000 miles, they'll do it very similarly to what Roush has recently started doing. Based on the thread I read on this forum from a guy who looked into it, buying the Roush tune went something...

resonator delete sound level Dave, your exhaust sounds like just what I'm after. Just a small, only mildly intrusive sound increase at idle and cruise, but appreciably more guttsy sound when I stomp on it. I figure that a little better flowing exhaust will also help me gain back the pound of...

Resonator Delete - facts and opinions 1. Does anyone know of a dyno test comparison of the stock Mustang ecoboost exhaust VS a stock ecoboost Mustang exhaust with a resonator delete Y-Pipe? What are the gains if any from removing the resonator? I'm looking for factual evidence, not opinions...

CAI or no CAI I've read a lot of the CAI posts from both consumers and sellers regarding the benefits of CAI for the ecoboost Mustang. Independent tests of the JLT and AirRaid systems, for example, have shown decent benefits. Then I read that CAI systems for the ecoboost are gimmics, don't...

roush power packs Thanks Buzzer for the information. Your replies were very helpful. Given Roush's take on the intercooler, it kind of makes me wonder if I made a wise decision to order an aftermarket (Mishimoto) intercooler for my stock ecoboost this week when they had the 40% off sale. But...

Questions to Roush re: power packs 1. How much does the limited 3yr/36,000 mile warranty cost? 2. What does limited mean? What isn't covered that was covered before in the standard FoMoCo warranty? 3. Do you know about how much the dealer the ECU reprogram will cost the consumer? 4. Why no...

Roush power packs Are these the power packs Ford was supposed to be developing but, according to rumors, wasn't able to get past the CARB standards. Did Roush subcontract to develop them for FoMoCo.

danzo Obviously there is a wide variance in what people are reporting in gas mileage here. Some of that variance has got to be due, of course, to driving habits and driving environments. But, the variance reported here seems pretty extreme. I wonder whether there is more variance in the...

My trip computer, fuel monitor was set at .4 miles, presumably at the factory. I now have 5,500 miles on the car and the computer says I have averaged 26.1 MPG since then. I drive about a 50/50 city/highway mixture. Manual tranny. I keep it below 2500 rpm until the oil temp is in the normal...

danzo I noticed the same thing when I installed my Mishimoto catch can and thought the same thing as you, that maybe I'd broken the connection on the lower block. But while reading the threads on installing them on the driver's side, someone on another thread mentioned that the lower block...

Danzo Thanks Mishimoto for your supportive input. I'll keep checking every thousand miles to see if the quantity of catch increases and report back to this thread at that time. As of now, I only have 4,500 miles on the engine. It will be interesting to track. Now, on to the intercooler...

Danzo This is Danzo again, the origionator of this thread. Thanks guys for all the feedback, it is really appreciated. From what you've all said, I'm going to make a list of hypotheses (educated guesses based on information but not enough scientific information to make solid conclusions)...
