Home of the World's Fastest Full Interior K04 powered S4.
We are also the home of the World's Fastest Full Interior K03 powered S4. Coincidence?
See our Projects page for more on the cars.
We are the only tuners that specifically
tune for the aggressive nature of a Manual
Boost Controller without using a TCD(Throttle Cut Defender).
How?
1) Aggressive fuel MAPs to match the boost ramp associated with a manual boost controller.
2) Fully opening the throttle earlier to get your car leaving hard without revving it extremely high.
Most chips use the stock 4000 rpm setting. This limits a car equipped with a Manual Boost Controller since a manual boost controller allows the boost to build faster.
3) A 7350 rpm rev limit on K04 powered cars instead of the industry standard 7190 rpm limit.
Why a higher limit, well it helps you carry out first gear longer on a hard tire spinning launch and helps you avoid the dreaded rev limiter and ruining your launch.
4) Do you really think we will reveal all our secrets?
BOTTOM LINE: We don't just tune for 3rd gear pulls and dyno numbers. We tune for that and
everything else that gets your car to perform at its highest potential, hence our results

NOTES:
Due to all the variations from the factory for MAF sensors, etc and the fact that many people
already have Stage 3 / K04 Fueling please be ready to give us a complete list of all your current parts.
For those who already have Stage 3 fueling please contact Jason@jhmotorsports.com
so we can evaluate what we might be able to re use from your current kit, if anything.
For K03 Powered S4s, we can do a chip for you. We have excellent files, one of which
was used on Dan's record setting K03 car, which ran a best of 12.28 @ 114mph.
We use VAST Performance software and work hand in hand with them to develop
our own innovative tunes.
