The Power Upgrade Stages
PU stands for Power Upgrade. Our McLaren tuning packages come in four stages: PU-1, PU-2, PU-3 and PU-4, each focused on a different power level. Depending on the stage selected, an upgrade can require exhaust downpipes, catback systems, ECU tuning, fuel upgrades and ignition system upgrades.
Each upgrade is specifically set up by us to deliver the ultimate driving experience while always keeping engine safety in mind. Every package starts with a baseline data log and ends with post-install logs and a road test before the car leaves.

Fuel System Upgrades
