Using this method a tuner can optimize performance far more efficiently for any person vehicle, no matter what the spec. Of course This is often a favourite with significant-powered monsters and racecars, and likewise useful in diagnosing any troubles there might be.
‘Phase three’ and previously mentioned are essentially the most major remaps. These will work with big engine upgrades — Believe new turbo units and new internal elements like pistons — to extract critical performance from the auto. Because of this, these can cost 1000s of pounds.

No two cylinders are alike in the majority of engines. Manifold styles, variances in compression ratio, port-circulation variations and difference in cylinder-to-cylinder cooling can make Each and every cylinder perform differently.
