I keep hearing about a mysterious "chip" that opens up the engine perfomence.Yet no one can tell where of how I can get it. I have the 03 V-6 coupe and there are few upgrades available. AEM has nothing in the EMUs' for my year. Is this "chip" an automotve "spanish fly"?

 

The only real chipping with newer cars requires solder work and a chip burner. Otherwise you have to replace the ECU to get any gains that way. But you cant really expect much out of a stock engine but by changing the ECU. There are also air fuel controllers which alter the sensors to change the fuel map. Not many vehicles get 20 to 30 hp just from chipping a stock car. It usually requires increase intake exaust flow, increased bore/stroke, turbo setup, things like that. You could increase the amount of fuel that goes in but if its not fully burned its being wasted and that doesnt promise you will get a benefit from from that.

 

I've already done the cold air, catback and throttlebody. I'm thinking about bigger fuel injectors, but that would need some sort of piggyback onto the ECU to be able to use all that fuel. Peformance Accord does have cams (regrinds) and prepped heads, but I don't want to go that far, I still need a daily driver. Any suggestions as far as "simple" bolt ons?

 

I don't think you'll see to much of a difference with injectors. I would consider doing your ignition system before the injectors (which should be fine on an N/A motor). You'll probably notice that more and it should be around the same price.

 

if you increased the throttle body size and didnt bore out the plenium / whole intake manifold you have kind of a unused mod there. Because the stock throttle body is the exact same size of the plenium entrance.
