<P dir=ltr style="MARGIN-RIGHT: 0px">1. I've noticed that there are a few companies that make intakes for the A4. Does anyone have these and did they notice any real improvement in throttle response/ engine rev-up (or is there actyally an improvement in power)? </P>
<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">
<P dir=ltr style="MARGIN-RIGHT: 0px">There's a lot more you can do for better upgrades than an intake on an A4 1.8t. </P></BLOCKQUOTE>
<P dir=ltr style="MARGIN-RIGHT: 0px">2. How worth-while are the chips that I've seen online? I noticed that there is one for both the TripTronic and the engine. Should they be done together?</P>
<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">
<P dir=ltr style="MARGIN-RIGHT: 0px">The chips are very worthwhile. The make the car fun to drive. The tipchip and the engine chip do not have to be installed together. Installing either one separately is perfectly ok. If you are still under warranty I'd suggets you read some posts on Audiworld concerning voiding your warranty - just so you have all the facts.</P></BLOCKQUOTE>
<P dir=ltr style="MARGIN-RIGHT: 0px">3.Does the By-pass valve that PES offers do anything useful or just look pretty? </P>
<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">
<P dir=ltr style="MARGIN-RIGHT: 0px">No idea on the PES valve. But if you get chipped, you will want a stronger BPV. The stock one will die after a while.</P></BLOCKQUOTE>
<P dir=ltr style="MARGIN-RIGHT: 0px">4. Has anyone replaced their exhaust with an aftermarket unit? Same questions as with the intake mod. </P>
<BLOCKQUOTE dir=ltr style="MARGIN-RIGHT: 0px">
<P dir=ltr style="MARGIN-RIGHT: 0px">I haven't, but its a common upgrade after a chip.</P></BLOCKQUOTE>

The display in your console has died. Thats expensive to replace. I guess you could do it yourself, but my understanding is that you need to buy the full console.
