    What is the best mod

    I love the SCT tuner I have, lets me control shift points, shift hardness, ignition timing curve, idle, speedometer- all kinds of crap. I'm sure they all do that nowadays. It's a must have for sure.

    Major Lack of Power

    I'm guessing that he did, I think he said it ran great after changing the gaskets except for an occasional misfire which prompted him to change injectors and COP's. I'm suspecting wrong OR faulty injectors. Besides that, possibly a sensor that's not fully connected, and I think he eliminated...

    Couple of dyno charts, may help some folks

    Did your tuner use a premade tune file, or did he write it based on the dyno runs and what a/f ratio he was seeing? I'm wondering because I have dual exhaust and the GOTTS mod, and I don't think a premade tune file will be nearly as accurate as dyno tuning. The Gotts mod is getting me pretty...

    Fuel pressure regulator swap

    It's mechanical, the pump should have a full 12 volts, there's not a fuel pressure sensor on the rail. All I have is the dampener that looks like a regulator. I was thinking a little more about my idea, and it won't work unless I regulate it before the filter. If I install the regulator...

    Major Lack of Power

    maybe one or more injector base o-rings are missing, torn, or leaking?

    Major Lack of Power

    I would triple check that you have the correct part # injectors..what part # did you install?

    Fuel pressure regulator swap

    I was thinking some more about this and have another idea. I can replace the pump with the high flow unit (no matter what I have to do that). Then I'll modify the built in (in tank) fuel regulator so its not regulating, just full output. I'll leave the factory stock fuel filter with return line...

    Fuel pressure regulator swap

    OK, I've been learned a little bit today... I think I understand the fuel system much better now. Looks like its a mechanical returnless system. Also looks like the filter has a built in return line to keep the pump flowing and cool since it provides much more fuel than is actually being used by...

    Fuel pressure regulator swap

    I'm trying to figure out how to change the stock fuel pressure regulator. The stock one looks like it's actually built into the fuel rail as an assembly and not replaceable. With my supercharger install project, I need to install an adjustable aftermarket regulator with a 1:1 pressure ratio...

    Vortech install on 04 EB 5.4L

    What kind of fuel pressure regulator are you running? Can you bump up the pressure to increase the injector flow rate so that it imitates 52# injectors (like the FMU does)? In my case, I have stock cams, intake, and heads. I don't have headers either, and I'm running stock rpm range. I won't...

    Momentary Hesitation

    Ok, mine also was doing that one time. It would just turn off almost completely for a 1/2 second while driving on the highway. It was like I shut the key off. It started getting worse/longer and I put in neutral while it was "dead". I stepped on the gas and it wouldn't respond or go above 500...

    Momentary Hesitation

    On my 98 explorer it had a bad spark plug wire, and when it misfired sometimes the check engine light would flash and sometimes it wouldn't. It's supposed to flash a certain number of times so you know which cylinder. Not sure if the expedition does that too. Last week it had the same problem...

    Momentary Hesitation

    I had same symptoms and problems on mine. It started immediately after I washed the engine- big mistake. The seals for the spark plug leads had been in bad shape and allowed water into the spark plug cavities on 5 cylinders. I cleaned out the water and cleaned the spark plugs, and it still had...

    Vortech install on 04 EB 5.4L

    I have a new problem, the harmonic balancer was missing from the kit. Its discontinued from Vortech. Vortech told me that on the 2005 5.4 kit they no longer need to replace the balancer because it's already shaped to fit their pulley and it bolts right on. Since Vortech no longer makes it, does...

    Vortech install on 04 EB 5.4L

    You don't normally see the two pipes under the truck when its on the road. You just see the outlets by the rear fenders. That's why I took that picture looking under the rear of the truck from behind, so that you could understand how the guy was able to route two pipes. BTW, since this...

    Vortech install on 04 EB 5.4L

    The exhaust guy does a lot of custom work for the local hot rodders, and that was the easiest way for him. He said if he had more time (and more money) he could try running two pipes in the stock single pipe location and dumping them both out on one side. For me, I like the look and sound from...

    Vortech install on 04 EB 5.4L

    Exhaust pics I finally got some pics of the exhast online... here they are The guy who did it is very picky about making perfect "Factory like" fit. They don't rub anything or make any noises at all. The center of the rear is solid mounted to the chassis so it doesn't move, so we...

    Vortech install on 04 EB 5.4L

    Great info guys thanks. I'm looking on ebay and amazon, there's a ton of MAF sensors all 90mm. Is there one thats better than the other? Am I better off just going to the parts store in town and buying one?

    Vortech install on 04 EB 5.4L

    I talked with my guy who's doing the computer programming for me on the dyno today. He said the old school way of tuning was using a FMU and the "recalibrated" MAF sensors- but that was before it was so common to reprogram the computer. He's going to just reprogram the fuel curve, injector...

    Vortech install on 04 EB 5.4L

    I'm running into another small problem/question. I can't seem to figure out which intercooler size will work best. I'm assuming a 2.5" in/out is fine since this engine won't go above 5,000 rpms. I'm not building a drag racer, but want it to be built properly and efficiently. Not sure what CFM...

    Vortech install on 04 EB 5.4L

    I had looked up the stock Lightning injector part #'s and all the specs I could find said they were only 24#, and my stock 5.4L were 19.04#. They must rate them differently and at different psi's. The ones I bought are brand new Motorcraft 4.6L supercharged mustang stock injectors, rated 39#...

    Vortech install on 04 EB 5.4L

    Hey all, I'm looking for input from anyone who's already done what I'm about to do. I just bought a used Vortech kit (which was missing some parts). It was a V-1 kit for a 97-03 5.4L, and they had upgraded the blower to a V-2 (quiet) blower. The blower looks like it's brand new off the shelf...

    New Dual Exhaust (again)

    Well I wrecked my last expedition and have a new clean slate to work on. This time I'm doing true dual exhaust, last one had 2 in 1 out. Since there isn't much room to fit dual without removing the spare, we had a little bit of a project. I'll post pics soon, but basically what we did was run...

    More MPG

    My 2003 2 wheel drive 5.4L got worse mileage than my 2004 4wheel drive does. Both had the same gearing and engine/transmission. The 2003 had 160K miles on it, the 04 has 103K miles. I did the GOTTS mod on both trucks, gained power but no economy. The 03 gained mpg with the Spintech exhaust and...
