Lexus GS 450hWhat we can do for this one, the parts that fit it, and the other engines in this car.

We do not have a Stage 1 file on record for the Lexus GS 450h yet, so we are not going to quote you a figure we cannot stand behind. Send us the registration and we will tell you what is available for your exact engine.

Stage 1 on this engine

We have not got a file on record for this exact engine yet

Every other figure on this site comes from our own dyno or our file supplier's tested data. For the Lexus GS 450h we have neither, so there is no honest number to put here - and we would rather leave it blank than invent one. The factory figure is 345 bhp.

Send us the registration and we will tell you what is actually available for your car, including whether a file exists for your ECU. If we cannot help, we will say so.Check my registration →

Questions

Lexus GS 450h remap questions

How much power does a Stage 1 remap add to a Lexus GS 450h?

We do not have a Stage 1 file on record for the Lexus GS 450h, so we cannot give you a figure for it. The factory figure is 345 bhp. Send us the registration and we will tell you what is actually available for your exact engine, and say so plainly if the answer is nothing.

How do I get a price for a Lexus GS 450h remap?

Put the registration into the calculator and it prices Stage 1, 2 and 3 for this exact engine, or send the form on this page and we come back with a fixed price, usually the same day.

Is a Stage 1 remap safe for this engine?

Stage 1 stays inside what the standard turbo, injectors, clutch and cooling were built to take. The figures above are the calibration we run, not a maximum. The car is checked for stored faults before and after, and the original file is kept so it can go back on.

Does remapping a Lexus GS 450h affect the battery or electric range?

No. The remap changes the petrol engine calibration only. The high-voltage battery, motor and charging are not touched, and EV range is unchanged.

How long does it take, and can it be reversed?

A Stage 1 remap is around 2 hours, in a single visit. Add a dyno session and allow 4 to 5 hours. The original software is stored and can be restored on request.
