    Problems with Throttle by Wire

    None of the local parts stores have it in stock, but I found the part number on Rockauto which would have taken a week to get here. I found the same one made by Dorman on Amazon, will be here tomorrow supposedly. Was like $55, part # 699-132. I'll update if it fixes the problem. That would be...

    Problems with Throttle by Wire

    It's a 2008 EL XLT. The pedal has multiple wires so maybe the ones showing the output to the scanner are not the same as the output going to the computer/ETC? I'll look for the pedal sensor and replace it, see what happens. I tried to do a throttle calibration but not sure if that did anything...

    Problems with Throttle by Wire

    Have this issue where I step on the gas lightly and nothing happens, then at about 1/4 throttle it lunges and takes off. Looking at it on the scan tool, the pedal sensor shows a perfectly smooth transition from 0-100%. The sensor called "R Throttle" whatever that is, shows 8% at idle, will move...

    Intake modification- 08 Expedition

    Just saw your message. It only took a few days to get here though.

    Cat back Exhaust upgrade

    I finally gave up on the CGS muffler after trying to make it sound the way I want for months. I had installed an Auger type resonator inside the pipe but it kept coming loose and rattling. The CGS muffler was also corroding very badly. The most annoying part of the system was the horrible drone...

    Intake modification- 08 Expedition

    Yeah, the design of the truck intake on the 5.4 engine is all about low RPM torque. Even a bigger TB still won't make much of a difference. The intake itself is such a weird design that it's causing the engine to build low end torque, but no real power above around 4300 RPM. The main benefit of...

    Cat back Exhaust upgrade

    I don't have the Gibson system, I waited several months for it even though they took money out of my bank to pay for it- as if it was actually available and for sale. After months, they shipped it a week after I canceled the order. They then made me wait another week for it to get delivered...

    Cat back Exhaust upgrade

    I'm sorry I don't have any pics of the auger installed. I moved it to the inlet side of the muffler now too. Mounted close to the tip I believe was causing a lot of ticking/hissing sounds that I didn't like at idle. It sounded like an exhaust leak. I think that's because there's a hollow pipe...

    Cat back Exhaust upgrade

    Just saw your message from last month....sorry. I bought the auger from Speedway Motors. It was the 3" one. It needed to be filed down a little bit to fit in the exhaust pipe. One time it actually fell out of the pipe but luckily it was when I started the engine. It blew into the driveway. I...

    Intake modification- 08 Expedition

    I recently just rebuilt my engine in the truck. Slightly upgraded the cams and exhaust while it was apart. Today I changed up the intake a little bit. The stock intake was nice and quiet, but the short path from the airbox to the throttle body was full of many J-tubes and other types of noise...

    Just ordered my 5 Star Tune - Any advice?

    Just from experience, message the guys (Shawn) at SSi performance and get a tune from them as well. 5 star is weird, they're all talk until 4:45 in the afternoon and then ghost you until next week. They hosed me a while back, but SSi helped me out. Then a few weeks later they helped me again...

    Cat back Exhaust upgrade

    One final note on this install. I eliminated the drone noise completely. First I tried transferring the heavy weight that the factory had welded on the last section of the old tailpipe, the added mass sometimes cancels out drones caused by echoes in the pipe. That did not work. Today I put in an...

    SCT XCal 4

    UPDATE: On Monday, they day they said they were closed for Juneteenth, late in the afternoon I received a file with instructions to perform the update and recovery. I tried it and it actually worked. There was never any explanation as to why they didn't respond over the weekend like they told...

    Vibration

    I've had a few different vibration issues that only occurred during light acceleration and they weren't the coils or plugs. One problem was the cv joint axles being worn out and very wobbly. The other problem was the torque converter clutch being worn out. To check each axle you have to put in...

    Cat back Exhaust upgrade

    Update on the install: The exhaust system is built really well, excellent bends etc. The biggest problem is that they kind of threw it into a box with the absolute cheapest ******** clamps and hardware possible. The clamps bottom out and actually twisted, almost broke and the pipes are still...

    SCT XCal 4

    Recently programmed my 08 Expedition with an Xcal 4. I'm currently using tunes from SSI Performance. They (SSI Performance) are very quick to respond to any and all questions via text, email and phone. Over the weekend I was all ready to tow the boat for the day, Father's Day weekend, lots of...

    Cam upgrade

    I talked to (via email) Todd Warren cams about my build up. He had great knowledge and input, but right off the bat he had plans for me to change valve springs and put a high 2800 stall converter for the cam he wanted. I already told him I use it for towing not racing, and it's almost 6k lbs...

    Tuning Question (human interface)

    Just wanted to follow up on what is going on with the SSi performance tune, he actually worked on the tunes for me and emailed me two files within a few hours of me paying. I can't believe it, I waited weeks from the other place. He said to let him know if it's gonna do what I need, and if not...

    Cat back Exhaust upgrade

    UPDATE: Yesterday morning I had gotten an email from Realtruck saying my Gibson exhaust system was going to be delayed another 4 weeks. I called and canceled my order. Then bought a CGS exhaust system from Car ID and it's already shipped. However, yesterday afternoon at 6:00 I get an email from...

    Tuning Question (human interface)

    I can't say how all the products operate but I can tell you how mine works. I have an SCT Tuner, model is X-Cal 4. Was around $400. Then you buy custom tune files and they will email them to you. You load them on your tuner and plug it into the vehicle. You then load it into the vehicle, and...

    5Star Tuning came through.

    Oh ok, that's probably waay beyond what I should be messing with. The shop like the trans shop, or dyno place can plug in and change pretty much whatever they want to using HP. I know nothing about fuel maps, and what load it takes to turn off the torque converter lock during acceleration, or...

    5Star Tuning came through.

    When 5 star sent you your Xcal files, were they ready to go or did they send you a "test file" first and want you to use it for datalogging etc.? I just waited for two weeks for them to send me a tune (I actually ordered 3 files) because they apparently only had one guy who was capable of...

    Cat back Exhaust upgrade

    Since I just rebuilt the engine I figured I'd go ahead and upgrade the exhaust too. So after comparing brands I had originally decided on the Gibson system. I ordered the kit through "Real Truck" in Miami. Their website and order confirmation both said to expect the order in 7-14 days. They also...

    5.4 Engine buildup- Any thoughts on upgrades etc?

    Well the Ford Racing cams aren't going to work out. 5 star said they'd be able to make it idle in gear with the stock converter but... No way. In gear it jumps and surges and bucks, have to power brake it. It feels the same as stock off idle to 3k. Falls dead at 4500. Basically the truck has...

    5.4 Engine buildup- Any thoughts on upgrades etc?

    Looking like I can use both in the single location. I'm waiting for 5 star to give their opinion before they send a tune. Also side note... Put the comp cams on the side. I went with the Ford Racing 6550 - 3v cams.... Sorry, wanted that sound lol. If it doesn't work out I'll swap in the comps...
