MOD Chip 2001 Grand AM 2.4L

i came across this mod chip and wanted to know exactly what they do that gives your car more horsepower. How do they effect fuel milage? Is it worth it?

pretty much all the "chip" does is make the engine run rich....which will decrease gas milage but increase performance....if your looking for performance...id get a CAI, or exhaust, or something along those lines....

Here ya go, I discussed this in a post a while back:

so im better off getting a CAI? because where i live during winter we average a 10 degree F for a temp and it's not uncommon to go below -30F.

i know this is kinda off topic but now that i seen that picture of that red grand am. i might get a new set of rims and tires this summer and wanted to know what size rim's are tires i fit on my car

Yes, you're deffinately better off going with an intake.

By the way, I would specifically reccomend a warm air / short ram setup, especially in your situation. Read this thread - me and some other guys thouroughly discussed the different pros and cons of different intakes:

CAI is for low end. and WAI is for high end? im looking for low end and up here where i live winters get as cold as -40F and as hot as 90F in summer. how does air temp effect a WAI if im looking for greater low end

no, WAI gives you better low end, CAI gives you better high end. Air temp affects a WAI much similar as it would a CAI - colder air coming into the engine through home-made "cold air lines" will bring cooler outside air to the intake - colder = denser = more fuel = more power.

But like I said in that thread, WAI = better low end.

If the intake air is comming in less than 32 degrees your engines pc will compensate air/fuel automatically. My GA runs best in -40c/-40f outdoor weather conditions and my intake temperature drops below -45c. I have to let it run to warm up before ripping or it can make it run crappy. I used a indoor/outdoor thermometer to test intake air in different conditions. Hot days to cold days here in canada. I guess Im saying I disagree with temperatures affecting the a/f cus like i said the pc compensates for those changes.

In all the years of using and researching cai , wai or ram air I have never seen a scientific study to prove that cai actually increases hp or as a comparison to wai or as I like to call it short ram air. There are no studies to prove the benefits well that I can find anyways. Please post a link to show a study proving it Im getting tired of looking.

Hey Mark - haven't seen you around here in a while :). Thought ya died or something. LoL.

Well I never met it actually increased the A/F ratio, Mark, because it would then in fact be running rich. What I did say was that the colder the air that you're sucking in, the denser it will be, fitting more in per stroke, and your computer will compensate accordingly by using more fuel, though the a/f ratio will still be the same. So the increased power isn't from more fuel per se, but for more air & fuel (the ratio still being the same), so you've got more power per stroke due to more air being crammed in each time. I think we're both on the same page, i just wasn't clear with some stuff that I've said.

lol no I just moved and I am a poor mofo. I want to research cai on N/A engines. Most folks figure short ram is the way to go these days. I think if it sucks cold air it wont get heat soak as quick and may dissapate it more quickly. Im all about heat dissapation myself.

^ ^ Yeh that's true. That's why on my warm air / short ram setup, not only do I have "cold air lines", but I also have a homemade sheet-metal "cold air box" to help to prevent that engine heat soak.
