ECU Remap / Chiptuning
What we do
We write a custom map on our own dyno — fuel, ignition, boost and rev limiter, tuned to your car, not a generic file.
What it does
Sharper throttle, more boost, no flat spots anywhere in the rev range.
+0HP
+120 Nm
Step 02 / 05
Turbo Upgrade
What we do
Hybrid or larger turbochargers with upgraded actuators, matched to fuelling and the map.
What it does
More air at high RPM — top-end pull that keeps going instead of fading.
+0HP
+140 Nm
Step 03 / 05
Intake & Intercooler
What we do
Carbon cold-air intake and a bigger front-mount intercooler.
What it does
Cooler, denser air — consistent power, lap after lap.
+0HP
+25 Nm
Step 04 / 05
Straight Pipe Exhaust
What we do
Titanium straight pipe, downpipes and valved tips.
What it does
Less back-pressure, faster spool — and that sound. Pops & bangs optional.
+0HP
+20 Nm
Step 05 / 05
Brakes & Suspension
What we do
Big brake kit, adjustable coilovers and a proper alignment.
What it does
Power you can actually use: stops harder, corners flatter.
