Chipping is best from APR (www.goapr.com) unless you plan to just go nuts. If you plan on trying to have some insane car i might sugest GIAC as your chip tuner. I have to say that I only have an APR chip (with the stock, 93 octane and 100 octane programs) a forge diverter valve and a neuspeed intake on my 01 audi tt 225 and with 100 octane I run 13.6 in the quarter at 102. Don’t do body mods they don’t look right on audis instead consider debadging it’s way hotter, clean is the way to go. ECS tuning (www.ecstuning.com) should have you covered all the way with everthing else and they have excellent customer service.

First, I would suggest checking out the AudiWorld website. It is the main website for Audi enthusiasts and is a great source for Audi info:

AudiWorld has forums for the different models/years. Excellent place to read up and ask questions. For your B7 chassis, go to:

My opinion:
For chipping, most people go with either APR or GIAC (links below). Everyone has their own opinion about which chip is best…but IMO these are 2 of the best. Both have chips for the B7 A4. I would recommend going with whichever one has an authorized reseller/installer closest to where you live.

For wheels, that’s really up to your taste/style. Many Audi drivers prefer a cleaner look (i.e. less ‘bling’). I personally like the Audi RS4 wheels. Also, the HRE 895R wheels:

For body kits and exterior styling, definitely check out LL Tek Motorsports. They carry quality aftermarket Audi products from Rieger, Caractere, etc. Their prices are reasonable and they do excellent paint matching for exterior parts. Just don’t ***** a giant wing on the trunk….most Audi owners would agree that a clean look is better.

For suspension, there are multiple options…1 is Stasis Street Sport coilovers.

For overall Audi tuners (turbo upgrades, chipping, suspension, exhaust, etc), check out AWE and APR. Both have dealers around the US.
