Lexus GS Stage 1: 250 hp → 270 hp

Factory output for the Lexus GS 300 is 250 hp and 310 Nm. A Stage 1 remap targets 270 hp and 330 Nm — 20 hp (+8%) and 20 Nm (+6%).

Those are the figures we work to on this engine. They are a starting point, not a promise: the number we hand back is the one your car makes on our dyno, measured before and after on the same day, in the same conditions.

What 20 hp changes on the road

Taking the 300 from 250 hp to 270 hp, with torque from 310 Nm to 330 Nm, is felt less as a bigger top number than as a shorter wait for it — the engine answers the throttle sooner and holds the pull further up the rev range.

Tell us the exact engine code and we will say precisely what is on the table for your car before you commit to anything.

What Stage 1 involves on a Lexus GS

We read the ECU, log the car as it stands, and put it on the dyno to confirm the 250 hp baseline — a tired or faulty engine gets diagnosed before it gets mapped, not after.

The calibration is written for your car, not pulled from a file library. We adjust fuelling, ignition timing and throttle mapping, then re-run the dyno to verify the 270 hp and 330 Nm figure and check knock, lambda and temperatures under load.

Turnaround is same-day for most cars. Stock file is archived, so the car can go back to standard whenever you want.
