In-house software
Every file is developed in-house and tailored to your exact vehicle. We never load a generic third-party file.
More power & torque
Real, usable gains — a turbo diesel commonly picks up 25–50 bhp and a big slug of torque at Stage 1.
Better economy
Turbo diesels can see up to 20% better MPG, because there's more torque low down and you use less throttle.
Dyno developed
A 2WD rolling road and an independent truck dyno — gains are measured with full data logging, not guessed.
