Who said a Lexus has to stay factory?
A smoother Lexus IS250, made sharper where it matters.
This Lexus IS250 came in to Paramount Performance for a performance remap, giving this naturally aspirated V6 a more responsive and enjoyable drive.
From factory, this Lexus IS250 produces 208 BHP and 252 Nm of torque. After tuning, this vehicle gained an additional 20 BHP and 18 Nm, taking it to around 228 BHP and 270 Nm.
The IS250 is already a refined car, but a custom ECU remap helps bring out more of its character. The aim here wasn’t to make the car feel aggressive or uncomfortable, it was to improve the way it responds, pulls and drives day to day.
With the added power and torque, the car now benefits from sharper throttle response, improved drivability and a more connected feel through the rev range. It’s the sort of upgrade that makes the car feel more alive without taking away the smooth Lexus feel that makes these cars so nice to drive.
Every vehicle is tuned properly and professionally, with the calibration suited to the car itself rather than using a generic one-size-fits-all file.
If you own a Lexus IS250 and didn’t realise it could be tuned, this is your sign to get in touch.
Whether you’re looking for better response, improved drivability or simply want to enjoy your car more, Paramount Performance can help.
