Audi B6 A4: AudiWorld's project car update

"AudiWorld" also made an update to their Audi B6 A4 project car.

Thinking back to the beginning, when we first laid our eyes on the B6 platform A4 1.8T Ultrasport, we remember the feeling of satisfaction regarding the aesthetics and the aggressive look. Similarly, when we first sat in the car we were mesmerized by Audi’s class leading fit and finish. The only small drawbacks were the funky cup-holder design and the plain-Jane seats that look more apt to belong in a base Jetta than a loaded Audi A4.

All the goodness came crashing back to earth when we turned that ignition key for the first time and experienced the painful lack of guts under the hood. It was then and there that we came to the conclusion that something MUST be done to get more horsepower and torque into the vehicle. Thus began our engine performance tuning quest, a quest that many 1.8T owners before us had already made.

The chipping program options on the market today reflect the maturity of the 1.8T platform. Five years earlier the field of tuners offering bonafide programs was literally half the size. The advantage serves the consumer well since owners can choose from a number of very nice chip programs – everything from mild to wild (and everything in between).

For this project we considered some of the more aggressive programs out there, knowing that the more established tuning companies out there would probably be best at squeezing the most out of the 1.8T engine. The stage 3 kit was briefly considered but the car is first and foremost a daily driver, we backed off the stage 3 kit and decided a stage 2+ system would be sufficient for our needs.

In the end, we literally flipped a coin and the fX program from GIAC incorporating bigger (380mm) fuel injectors was chosen. Having previously owned chipped B5 platform A4 1.8T cars in the past, we were looking forward to comparing the chip tuning potential of the B6 versus the B5. The butt dyno anxiously awaited our subjective testing.
