well said.

 

i have an adc performance chip in the mail for a protege 98 ill let you know what i think they are full money back garenteed no matter what so ill see how it goes and they are dyno tested

 

The thing about these chips is that if the return any gains at all (immediately after installation), the OBD-II system will sense the new parameters and then readjust your engine to bring things pretty much back to where the were before you put the chip in. Do a before and after dyno run, and then perform another dyno run a month or so down the road and you'll most likely see the numbers back where they started.

Long story short, the only way to add meaningful power to your engine is to invest in a full forced induction system, and that is going to be a couple of thousand minimum assuming you can do the work yourself.

 

Dylan - you are not going to get any gains from a $30 item. I have the Hypertech unit and it overcomes the drag of the a/c. Without the a/c on you do feel a difference but if you want a big boost you need to sell your car and buy a Speed3.

 

Iv'e been attempting to research this because I've really been wanting to add a chip so long as it works so far from what i've seen and been told is that 1 it cant be a cheap chip because their rip offs it has to be fully ajustable 2 it has to be put on properly usually dyno to make sure everything is in sync otherwise there will probably backfire which isnt good and 3 there are different stage chips anything stage 2 and up from what I've seen usually requires an after market intake and can possibly be really dangerous for youre engine if it isnt set to fit, I've also seen that when looking to buy one that if the year and make as well as questions about you're car arent asked then youre being ripped off I bought a pretty expensive a pretty expensive aftermarket k@n intake that I can seriously see a difference with when i rev the engine you can really hear the thing suck air in like a champ so when I heard about the chip I got excited I'm just hoping it's not all a scam

 

Uhhh, what?

Dude, sentences, paragraphs and punctuation are your friend; use them, please.

Long story short, for a normally aspirated engine with OBD-II controls, chips are a scam.

 

I recently bought a PCT Stage 1 FOR MY CX5. I installed it, but the data light never stayed on(all 3 lights should be on). PCT wanted me to troubleshoot it myself by installing it on a different car. But wait, I bought this specifically for my car? Was that a scam? When I ask for a replacement, they said they will send me a return label. Later PCT sends me a message that since I am not willing to troubleshoot it, I have to pay for the return label. And then when they receive it, they will test it. If they found it to be a defect, they will send me a new one free of charge. Why go to all this trouble? I decided to return it. PCT will probably charge me a 25% stocking fee. The best thing to do is not to buy from Performance Chip Tuning.

 

The answer not going to change from your first question about these today in this forum??
Performance Chip - Mazda Forum - Mazda Enthusiast Forums

And if you ask it on another Mazda forum I am sure I will also respond with the same. There are very few that use the actual ECU calibrating kits offered and know how to use them on many platforms not just Mazda
