Subaru Remapping Service

A Subaru remap gives the boxer engine more pull and a sharper throttle, whether that's a WRX on a good road or a Forester or Outback with a trailer on. Every map is written in-house by a qualified motorsport engineer, and because nearly every Subaru is all-wheel drive, it's measured on our 4WD dyno with every wheel driving.

Figures from our Remap Calculator. Your own car is measured on our 4WD dyno on the day.

Why Remap Your Subaru?

Subarus are bought for traction and toughness, on country roads and with a trailer on. A two-wheel-drive rolling road can't measure a symmetrical all-wheel-drive car properly. Our 4WD dyno drives all four, so your Subaru gets a true before and after reading. Our SUV and 4x4 remapping page covers the Forester and Outback for towing.

Subaru Petrol Engine Tuning

The turbocharged boxers in the WRX, older Impreza STi, Forester XT and Levorg gain the most, with more mid-range and a sharper throttle. The naturally aspirated engines in the BRZ and XV gain response. For a WRX, there's more to come from our performance remapping and a custom exhaust.

Subaru Diesel Tuning

The 2.0 boxer diesel in the Forester, Outback and Legacy gains torque for towing and overtaking, and a little economy on a steady run.

Pick your Subaru in the Remap Calculator above, or ring 087 744 2633 to book it onto the 4WD dyno.

What happens on the day

Check your Subaru in the Remap Calculator or give us a call, then book it in. On the day it goes on our 4WD dyno for a before run, the map is written for your engine, and an after run shows you the difference in power and torque.

If your Subaru is an automatic, ask us about a gearbox (TCU) remap on the same visit.

So I got a hybrid turbo from muchboost installed in my Mercedes c220 and was advised to get a custom remap on a dyno so I contacted John got it booked in and he also offered hydro clean as an option and It was worth every penny I couldn’t believe the difference it made plenty of power and ticking over like a dream thanks again

Can you remap the gearbox on an automatic Subaru?

Yes. Ask us about a gearbox (TCU) remap on the same visit, for quicker shifts and room for the extra torque.
