Where can I go to find a legitimate performance chip for my truck?

Asked by Jeremycw1 (1367 points ) July 12th, 2010

I want to increase the performance of my truck as much as possible, and a chip seems like a good option. Can you suggest a website or even a specific chip that actually works?? Thank you :)

This is my third attempt at doing this. I know nothing about Glasspack exhaust systems, but I do know about High Performance Exhaust Systems if that’s what you are wanting. I’d go with this http://www.flowpowerexhaust.com/performance/?N=10336+4294963364+1616+11920+9292 The Magnaflow exhaust has a more deeper throatier sound. You’ll get more horse power, more torque and better fuel mileage.

Also, since you are considering a new exhaust system, You should seriously consider a CAI (Cold Air Intake) and SCT X3 Power Flash, there are many different brands and I just happen to have bought that one! Plus! You get free tunes for life! (and I don’t mean music) Here are some other performance Parts and Accessories sites. I personally have used this company and trust them! www.autoanything.com http://www.autopartswarehouse.com/vehicle/2001/ford/ranger/xl/6_cyl_4-dot-0l.html http://www.horsepowerfreaks.com/performanceparts/Ford/Ranger also check out these Ford Forums. http://www.fordrangerforum.com/ you can get all kinds information, How to’s to trick out your pickup. or just Google 2001 Ford Ranger.

I have a 2007 Ford Mustang V6, manual trans. The first thing I did was to purchase a Ford High Performance Racing Dual Exhaust System, JLT Cold Air Intake. In case you don’t know, if you go with the CAI. You MUST purchase a Flash Tune, it will rewrite the on board computer chip because of allowing so much more air. Shoot, I have to go to bed, I am spending more time Backspacing then I am typing forward. I apologize for any typos, I am too tired to look and correct.
Alright, it’s waaay past my bedtime. Good luck and have fun!

@ thanks that was really helpful! I want to get a dual sport exhaust system now! I would just have to get it professionally installed ( I don’t know anything about installs)

Modifying your truck’s computer, either directly or through sensor overrides, isn’t going to do diddly for it without other modifications. On modern engines, this is how you make use of the power you can get from intakes, exhausts, cams, and other parts. Don’t get suckered by the junk sold on eBay or from those little ads in the back pages of magazines. Those things can screw up your engine.

Start with a cold air intake. That will give you the most power for your buck. From that point onward, you’re facing diminishing returns in terms of $/HP. Next up are headers and exhaust. You don’t need a reflash or engine management system until you’ve done quite a bit to your mill. Then you’re looking at several hundred dollars, maybe a grand, for the system.

@IchtheosaurusRex the thing is, chips are like 70–150 $ dollars, and I can install it myself. For a cold air intake its gonna run me about $300, and I’m not sure if I know how to install it. They look pretty easy to install, but i’m not sure. I was just looking for something that I could install myself that would boost performance at least a little bit.

@Jeremycw1 , what kind of chip are you talking about? There are hucksters all over the Internet selling “Performance Chips.” Here is what you typically get: a small device that replaces your IAT (Intake Air Temperature) sensor. The IAT sensor is a thermistor that your engine computer uses to determine how warm the intake air is. When the air gets warmer, it leans out the mixture and retards the timing to accommodate the lower oxygen content of hot air. When the air is cooler, it does the opposite – richens the mixture and advances the timing because you have more oxygen in cold air. This is why cold air intakes are a good mod.

Those so-called “performance chips” do nothing more than try to fool your computer into thinking the air is cooler than it actually is. it’s not nice to fool your engine computer. The reason is that running with too rich a mixture, and at advanced timing to boot, results in unburned hydrocarbons in the exhaust gases. The catalytic converter has to deal with those. Run too rich for too long, and you damage the cat = up to $1000 for a new one. Fortunately, you will probably get a code and check engine light from one of the O2 sensors first. That’s your computer telling you it’s not nice to fool the computer.

Don’t do it.

@IchtheosaurusRex I’m talking about a legitimate computer tuner… one that’ll go for about $300. I thought they were cheaper at first, but I was wrong. Do you think I should get a cold air intake or a performance chip tuner first?

@IchtheosaurusRex this is what I had in mind… although I’m not sure if I could find this for my truck. And I am starting to wonder if this would be better to install after I installed a cold air intake. I appreciate your thoughts on this!

@Jeremycw1 . as I mentioned in my first post, you want to do the mechanical mods before you start tinkering with the ECM programming. And a CAI is always your first mod. It goes in this order:

Cold air intake
Cat-back exhaust system
Header(s)
ECM programmer
Intake manifold & throttle body
Cams
Fuel rail and injectors

This is for a normally aspirated engine. If you want to go boost, it’s a different setup.
