At what point does a chipped a4 actually make a big difference? I'm getting my APR chip tomorrow and can't wait to find out for myself.

it works by remapping timing, increasing boost levels, and adjusting fro proper timing and air/fuel.

Your car will suddenly have power from 3k-6k. Big difference.

NA chips don't do a whole heck of a lot. They advance the timing, remove the speed limiter and require higher octane. NA chips usually don't add alot. Custom chips matching your other modification can make bigger changes, such as intake and exhausts.

The biggest HP gains come with turbocharged cars, which mainly comes from increasing boost. Tuners usually do the above things also.

Hope that helps.

so which chip returns the highest HP? how do you upgrade if you already have one?

I'm getting the EMCS with stock and chipped mode. I hope it's worth the money. Thanks for the info.

Next step will probably be the APR exaust. It look loke it only gives an extra 10Hp or so. Do you really think it's worth $899 plus installation?

for the money there is no other mod you can do to these cars to get anywhere near the HP and torque that the chip will provide.

You can't go wrong with either Milltek or APR... both very solidly buit great sounding and looking systems. Borla is cheaper but it's a fairly sketchy system.

ridiculously expensive actually. There are few other cars out there that have $800 exhausts. My friend paid $300 for a Borla for his Camaro. Aftermarket exhausts on Audi's are ludicrously priced. If I could do it again I would go with a custom exhaust.

Sell me your miltek and start again, simple as that.
