Each engine gets its own performance chip: GAN GT / GTL or GAN GA / GA+. Prices are per performance chip and include the current discount.

Not sure which engine you have?

The badge alone isn’t enough: in this generation, the same engine came with different horsepower ratings, each with its own calibration. Check the horsepower in your owner’s manual or vehicle documents and find the matching row.

Alfa Romeo 159 tune: what changes

About the generation

What makes the Alfa Romeo 159 special

Alfa Romeo 159 tune: which 1.9 JTDM do you have

First, check which 1.9 JTDM sits under the hood of your Alfa Romeo 159. Count the valves: the 120 hp engine has eight and makes 280 Nm, while the 150 hp engine has sixteen and makes 320 Nm. Alfa Romeo never sold the 159 in the U.S., so a 159 here is a gray-market import, usually in enthusiast hands. An Alfa Romeo 159 performance chip is matched to the engine, so each of these two gets its own GAN GT figures.

Among the diesels, Q4 all-wheel drive came only with the 210 hp 2.4 JTDM. Beyond those two, the GAN GT also covers the 2.4 JTDM at 200 and 210 hp, the 2.0 JTDM at 136 and 170 hp, and the 1.75 TBi at 200 hp. A gasoline 1.8, 2.2 or 3.2 V6 calls for the GAN GA+ instead. Sportwagon owners are covered too: it's the same engines in a wagon body, so the same performance chips apply.

FAQ

Alfa Romeo 159 tuning FAQ

What does the GAN GT add to a 159 1.9 JTDM with 120 hp or 150 hp?

On the 16-valve 1.9 JTDM, the GAN GT lifts 150 hp and 320 Nm to 194 hp and 413 Nm. On the 120 hp engine, the gain is 36 hp. Across turbodiesels like this one, GAN rates the GT at up to 30% more power. Treat those as rated gains for the engine type, not a dyno result from your car.

How much power does a performance chip add to the Alfa Romeo 159 2.4 JTDM?

Put the GAN GT on the 2.4 JTDM and its 210 hp (listed as 209 in the catalog) climbs by 58 hp.

Is a tuning module the same as a Stage 1 tune?

Not quite. Stage 1 usually means an ECU flash tune without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
