600LT ECU Tune
$2,999.00
Product Description
The 600LT is the fourth car to earn McLaren's Longtail badge, and it's the one that proved that philosophy wasn't reserved for the Super Series. McLaren brought the lightweight, track-honed thinking first shown on the 675LT down into the Sports Series, and once again the name says it all: 600PS, straight from the same 3.8-liter M838T V8 that powers the rest of the Sports Series, now paired with extended bodywork, a lighter exhaust, and a sharper aero package than the 570S it's built from.
Weistec's calibration for the 600LT is a software recalibration of that factory M838T, built to work with McLaren's own engineering rather than override it. Every factory safeguard, knock protection, thermal management, OEM diagnostic behavior, is preserved exactly as designed. Delivered with OEM-level validation, it takes this 600LT from a factory 592 hp and 457 lb-ft to 730 hp and 652 lb-ft, adding another gear to a car that was already built to be McLaren's sharpest Sports Series statement.
