★★★★★

"Stage 1 on my Hilux 2.8 — completely different truck. Pulls stronger from low revs, uses less diesel on the highway. Already paid for itself in fuel savings."

★★★★★

"Had my whole fleet of vans remapped. Killian came out to site, sorted everything in one day. Fuel bill dropped noticeably within the first month."

Brad T.
Fleet of 4 — Commercial vans
★★★★★

"Did my Ranger and my tractor. Both completely transformed. The agricultural knowledge these guys have is hard to find anywhere else in the South Island."
