looks promising but "if its too good to be true it prolly is"

 

GIAC

 

Check out CIAG flash chip upgrade. I just did it on my 01 S4. No soldering or messing with the ECU---all software. In addition, you can go back to stock mode with a push of a button. You also have a valet mode, kill mode and race mode (high octane fuel required).

 

NOD - Wondering what the car feels like after you chip it. I have always driven high HP Camaros and Vettes. Buying my first S4 this week so I think I will be doing some mods...but I want a pretty much stock ride and reliability. Is that possible with the chip? Also, is there any permanent record of the car being chipped in the ECU? Last, does it really wake up the car and make it come alive? I have heard it can add as much as 100 ft lbs of torque...but that sounds a bit hard to believe to me. Thanks for the advice.

I'm assuming that you are talking about a twin turbo v6 (b5).

Check out this info page from APR. It states some facts and characteristics, etc.

And yes, you will get over 100 more torque and over 60 more horsepower on pump gas, easy.

you will aslo blow your turbos waaaaayyyyyy faster than normal and you will of course void your warranty, but that is controllable.

 

Hey Dan:

Sorry for the delay with regard to getting back to you. What it feels like...What can I say, it is a different car in 2nd and third gear. A turbo in gerneral will be a very different feel for you than a normally aspirated engine. There is nothing like a turbo in 5th or sixth gear and you mash the pedal and the car still has pull! Second Question: If you go the GIAC route you can take the car back to stock with a push of a button (you have to buy the handheld flashloader) for reliability and better fuel mileage. Third question: NO there is no record of any tampering---the dealership will not even know. However, GIAC database will know as your VIN will be in their system.
Fouth question: Yes it wakes up the car! Do an oil change every 3,000-4,000 miles and your car will thank you for it. Most times I run around in stock mode but when I am feeling aggressive or want to put a smile on my face or make a Porsche dude Cry, I will chip it (you can do this while the car is running or at a stop light etc). After you chip it, put it on a Dyno and tweak the auto for maxium boost. Have them scan your auto for any errors afterwards. Enjoy!
