i just installed one of those in my friends audi a4... he said he felt a little more up top on the gears 2-5 weird to say.. maybe it helped a little i guess... what does it even do? i'm not even sure..

 

$500= n2o

 

not worth the money. it is just a resistor that connects to your IAT.
It's a free mod to advance timing. Not worth the $20 dollars. You can buy the resistors at radio shack for a couple cents.

 

Get laughing gas.

 

buy a wrecked 2g gst for 700 and start swapping

 

What's an IAT? Where is it? And can I really just use a resistor?

that is really all it is...stupid i know.

 

i would never buy that stuff and i can't believe people actually buy it too

 

Get some laughing gas or get some head porting done maybe a header.

 

To be different, I'm gonna say pick up an old style AFC for under $100, a Wideband for $200-300, and possibly a used knock sensor like the J&S Knock guard. Then lean the piss out of it on the best octane you can find.

 

Hahaha, that eBay listing says it will make your car up to 20 HP faster... I didn't know speed was measured in horsepower these days.

Anyhow, a good chip, JET, Hypertech, SuperChips etc. costs a couple hundred dollars, so I am kind of skeptical that a $9 one is going to do much...

See if any of those companies make one for the 420a.

I don't believe that it advances timing. There was a thread on this a while back and all these little resistors do is fool the ecu into thinking that there's more cool, dense air coming into the engine than what there really is, so the ecu throws in more fuel to compensate.

So if anything it would probably make your car feel sluggish in the lower and possibly upper rpm's.

thought it did the opposite and leaned it out

yep, rich is slow and lean is fast
