Our Services for Fiat

Fiat's 1.4 MultiAir turbo — the heart of the 500, Tipo, and Punto — gains 20-30bhp through optimised electro-hydraulic valve timing and boost pressure. The 1.3 and 1.6 MultiJet diesels see 25-35bhp with dramatically improved low-end torque, transforming these small-capacity engines for motorway confidence. The Ducato's 2.3 MultiJet is popular with commercial operators seeking better loaded performance without sacrificing the engine's legendary durability.

The Abarth 595 and 695 use Fiat's 1.4 T-Jet turbo engine with IHI turbocharger hardware that has substantial headroom beyond the factory 145-180bhp ratings. Our Abarth calibrations increase boost pressure, optimise ignition timing in the mid-range, and sharpen the overboost function for 25-40bhp gains. The result is an even more exciting pocket rocket — with the characteristic Abarth exhaust bark amplified by the extra power.

Fiat's MultiJet diesels — particularly the ubiquitous 1.3 in the Punto and Doblo, and the 1.6 in the Tipo — respond well to economy calibrations with 10-15% MPG improvements. The Ducato 2.3 MultiJet used extensively in motorhomes and commercial vans sees particularly worthwhile savings through optimised cruise-speed fuelling. We focus on injection timing and rail pressure refinement without reducing the available torque.

Fiat's 1.3 MultiJet is one of the most common small diesels in the UK and suffers frequent DPF issues from urban driving — the 500, Punto, and Doblo are particularly affected. The EGR valve on MultiJet engines is a known weak point, with carbon fouling causing rough idle and reduced performance. We diagnose whether the issue is filter soot loading, additive depletion, or EGR carbon, and apply the correct Fiat-specific software solution.
