Performance Chips. Do they work?

Hi All,
Do these 'performance chips' that I see advertised on this site actually work? I mean....'Up to 60 extra HP.....' by installing a new chip into my ECU is that really going to get me an extra 60HP? Or is it more like....'UP TO 60'....meaning I really get 1 or 2 extra, unless I put in a ton of extra high performance parts? Since i get crappy mileage anyway, how much worse could it get. And it says mileage is suppose to go up as well...so...before I spend money I dont have....do these things work, or is it all hype? Like the K&N Filter....where you also get....'up to an extra 15HP'....it is always 'up to'. And then you get 1 extra HP at most. Anyone? And is it that easy to install....and uninstall if it is not to my liking?

Like the other 300 threads, they don't work. I don't know why you worry so much about MPG's, you don't drive anywhere :D

Sorry ,i didnt know there was a huge post about the chip. For once I am looking for PERFORMANCE out of the car, instead of mileage. So as I said....'since I get crappy mileage anyway', and this thing SAYS it gives you up to 2-3 MORE miles per gallon, if I can get a ton of horsepower, AND get a tiny bit of more MPG, with this little chip for $69, why not try it? That is why i am asking if it works or not.
So...there is a big post of people talking about this chip? I will have to go hunt for it.

regardless of the price of the "chip" what they added to the "system" it is still basically a resistor from radio shack that is less than $.50 and all it does is change the intake sensor to trick the computer to run rich..

There have not been any in the past month or two, but we usually have one a week, and they all say the same thing :)

If those did "work" everyone would have them, that is for sure.

Are there chips for sale on this forum? I haven't seen any adverts here but the way tuning shops in Thailand offer them is as part of a package; a cold-air intake, new header and something like a 'Unichip' or similar for modest power gains, I've never heard of +60bhp being claimed, usually up to +10% of the engine's original power.

I bought the JET chip for my car. I noticed a great deal more low end power. Which would be great if I were racing people all the time. For in town daily driving though, it creates a very stop and go jerking experience though. Reminds me of the ecplipse I had with 300 whp. I just removed my chip because while I did find it effective and that it actually worked. It just wasn't an across the line gain.
I do want to add though that my chip wasn't a 67 dollar cheapy from some website. I paid 240 bucks for it from JET.

:o:o:o:o:o:o:o

If you want more power on the computer side of things get a tune. I've had one on my car for about a year now and it has changed the vehicle completely. Contact Vince over at Trifecta tuning and tell him Cory with the aveo sent ya.

That is only for 2nd gen aveos, or else I would have had one years ago.

Ah, good point :/ I always forget that the first gens aren't an option. Sorry, guess you're stuck with the bolt on side of things. Which isn't always bad ;P

Too bad there are no bolt on parts either :D

Tell me about it, we've got to do everything for ourselves lol. Not to say its any less fun! I need a header bad, too bad any of the places around me that could make one want a small fortune.

I know that feeling, 5 years of that and I am done lol

I know this thread is old but I ve been waiting for a response from JA Exhausts on their z16xer header, so I bought a Jet Stage 2 chip. Its a straight forward install but I cracked the sliding mechanism which caused some probs. It spuddered like hell and threw a CEL, but I reset the ECU and all is well. As far as performance it definitely does add power from 2000-4500the Rpm- there were kids out I wasn t pushin too hard. After only 2for miles of driving it feels like a little more pop than when I first added the intake so the 2 are a nice combo. Please dont hate on jet chips they r really not chips at all but risc processors( I beleive these processors where first used in the military). Now the big question is how does it compare to Trifecta.I bet $ they are pretty close cuz the E Z Flash tune is an "out the box " tune just like Jet, however if u custom tune in real time on the dyno Im sure Trifecta would be great.

If anyone cares the aveo ran great on the expressway ...It pulled harder than usual to 85 and thats when I let up, I usually drive 60-65. After work it once again threw a CEL. After playing with it I called Jet and told them Im getting a P0340 code for camsbaft sensor. The chip will be returned,& hopefully fixed . The customer service call was uneventful and I will keep u posted as to the result. If I am not happy I will pop a trifecta tune so the rest of us could get an honest reveiw from someone who has had both. I hope all gets fixed so the $ can go towards headers

Guess what the chip came back and the same ****... Im recognizing a pattern... these things r hit or miss n if its a miss u r f* cked. 3rd times the charm if they even take it...

Not to leave my complaint post undone. The 2nd chip is fine. My battery was going out causing my dash to look like a x- mas tree. I replaced the battery and all is well ...a lil quicker n no cels. I guess Im happy with my purchase, I will update if my mpg has improved in a month or so
