Well I have finally started modding my pickup. I have in the last two weeks added a Superchip, high flow cat, and a flowmaster 40 delta series.

The Flowmaster is a single 3 inch in, and dual 2 1/4 out. I have no pipes, just comes out of the muffler. The sound is way better and it is deep at low throttle, and gets louder and louder through out the rpm's.

The chip raised my shift point a couple hundred rpms, and I no longer have any problem revving the 351. It used to have a dead spot at 4000+ rpms, right before it shifted, but now it climbs without hesitation past 5000 if I want it to.

I thought I would lose low end with that open of a system, but I have all the low end I had before, and phenominal mid and high range compared to stock. I have a K&N FIPK coming, and soon pulleys.

If anybody wants to hear the truck, I can capture some video of it on my camera and edit it real fast for you. But I will need a place to host it, or just send it through email.

 

how hard was the chip install and can you get pics of both, and are your shifts firmer?

 

beastie,

The chip was a breeze to install. The longest part was cleaning the contacts on the trucks computer.

The noticeably quicker and firmer and 3/4 + throttle. At any less they don't snap, but they are quicker, and that's mainly due to my modest driving style (most of the time anyways).

I can get pictures of the exhaust for sure, but I don't know how well any pictures of the chip will show up because of the low light conditions of the kick panel. I'll see what I can do tomorrow.

 

cool thanks. Did you replace the front or rear cat?

 

Sounds like some great mods for a great FORD truck.

 

I got pictures of the exhaust system today, but I cannot find my usb cord that transfers the data from the camera to the computer. So I'll keep trying.

On the other hand I was able to capture a sound clip of the truck so if anybody wants to hear it just ask and I'm sure we can work something out. BTW, it sounds a lot better in person because the microphone that I had hooked up to the laptop wasn't all that great. But you still get the idea.

 

i would like to hear it. the 40's have a real good sound to them. between the chip and exhaust and fipk, it's some of the best mod money i spent yet. the chip being the best tho.

curt

 

I just ordered my chip from Mike today. Will have it tomorrow.

 

That does it. I'm going to reinstall my chip. I'll try cleaning the contacts, and see if that makes it better. I really miss that sucker.

Take care,

Chris you have a Jet chip huh. I looked at them. But the Superchip from Mike Troyer makes more power and works at any throttle position. He recomended ignition upgrades down the line, but I saw you said they made little difference explain...

 

Regardless of what you may have seen elsewhere, I can assure you that my JET chip works wonderfully at all rpms, and all throttle positions. I still am blown away by how big of a difference that little sucker made ALL THE TIME!!! Amazing!!!

As far as ignition upgrades, the simple truth is that the components used in the EEC IV system are as good, or better, than the majority of the aftermarket products available. Until you have added parts to your engine that dramaticallyincrease performance, or that will continue to perform beyond 5500 rpms, you don't need anything else. Ignition parts have a mystical reputation for bringing tons of extra horsepower to any engine, and this is just not true anymore. Back when the standard was a points ignition, a new Mallory or MSD system was like hitting a horse in the *** with a cattle prod! It made a huge improvement because there was a lot of room for improvement. BUT, with emissions standards as high as they are now, manufacturers are doing everything they can to develop a system that gets every conceivable ounce of energy out of every single spark. They want to burn up as much of the fuel as they possibly can in order to have cleaner exhaust emissions. The upside to this is increased performance. The downside to this is no real need for aftermarket ignition components. Wht do you think companies like MSD and Crane have started prettying up there parts so much? They give them awe-inspiring names, and anodized aluminum housings, and anything else they can think of to convince you that your vehicle will be so much better with them. Well, I guess that's kinda true. They do about as much for a nearly stock engine as chrome valve covers do.

PKWRD,

My question to you is which trucks came with the EEC IV ignition system? If you notice my signature, I have a lot of mods, and I've even removed a couple (chip, throttle body) but none of them are ignition related. From all I've heard about ignition mods, I'm really not sure if they're worth the money. So would a 1990 F-150 benefit just as little as a mid-90's Ford from ignition upgrades? Thanks.

 

I would recommend a new coil for you for two reasons. First, the mods you have made will allow the engine to rev higher than it would have stock. The generally accepted point at which the stock coil goes from excellent to marginal is between 5500 rpms and 6000 rpms. I doubt your truck will see revs like that very often, or for very long, but you are in the neighborhood. The second reason is the age of the stock coil. After 10 years, if someone wants to replace the coil, i don't have a problem with it. I replaced mine at 30k miles, but that's because I added the chip, and I didn't realize how good the factory stuff was.

As far as buying and instaling a new control module (ie: MSD, Crane HI-6, etc), the only way you would notice an improvement in performance is if your factory module is failing.

If it makes it any easier, another widely accepted limit is 375 horsepower. If your combo exceeds 375hp, get an aftermarket ign. box. If it doesn't, leave it stock.

Take care,
~Chris

 

Thanks Chris. I did just replace my coil with an Accel Performance Coil. I didn't add it because I thought it would boost my performance, though, I installed it because my stocker was starting to go. I honestly don't know how good of a choice that one was, but the guy I spoke with at Jeg's recommended it for me. Ignition related products are still an area of mystery for me. But I think between a nice coil, good plug wires and spark plugs and my ignition should be fine.

BTW, how often should I replace my distributor, or at least the cap and rotor? I can't quite remember the last time I touched that. :o Thanks again!

 

I replace my cap and rotor once a year. Make sure that the replacements you buy have BRASS terminals. This will cost a few bucks more, but brass doesn't corrode like the regular ones do. Wires are very important to. The best coil in the world won't do much good if the voltage can't get to the plugs! Also, and this is very important, make sure your spark plug wires are not touching each other. Use separators. This is most important for wires #7 & #8 on a non-HO 302, and wires #5 & #6 on HO 302's and 351's.

Take care,
~Chris
