Tiguan Tuning

"Easy Tiger"

The Tiguan is unusually placed as a fun family oriented SUV, many other manufacturers have seen the success of this niche and have created potential rivals to the Tiguan.

Described in the press as a soft roader it has the practicalities of an off roader when it comes to load space and access but the running costs are similar to a family car. On our speed bump and pot hole infested roads it is a sensible buy indeed.

The looks whilst controversial are generally appreciated and VW have virtually created a new model for their ever growing line up. We look at Tiguan tuning and report on the best modifications. Volkswagen Tiguan are popular cars and with a few sensible performance modifications you can greatly increase your driving enjoyment.

The Tiguan is a good project car to try. If you do your planning then you can create an awesome Tiguan but don't be fooled there are lots of performance upgrades out there that will simply not suit it read our unbiased guides first.

Handling/Suspension upgrades

Many Tiguan owners uprate the handling of their cars with performance suspension parts as a priority, this will certainly increase your enjoyment of the car.

If you set the toe out to around 1.5 degrees on the front, and add a bit of negative camber then cornering will usually benefit.

Drop the car by as much as 27mm - 37 mm and fit sports stiffer dampers, bigger drops will need other modifications in most instances.

When you drop a car you need a stiffer spring and this can make the ride quality unbearable.

The Tiguan doesn't look very good dropped anyway as the high suspension is part of the cars character so fit slightly stiffer springs and uprated components for better corning. An anti roll bar to the rear will also help. If anything Tiguan owners are jacking up the suspension for the full off roader look!

Engine Tuning.

The following performance mods are usually installed by our members, decide how far you wish to go in your tuning project before you start.

Getting the right uprated mods for your planned usage of the car is a time and money saver. Stage 3 motor sport parts just won't work well on the road making the car difficult to drive.

Stage 1 mods: Remap, Panel air filter, Alloy wheels, Sports exhaust, Lighter flywheel, Suspension upgrade (drop 30-40mm).

Stage 2 mods: Power/Sport clutch, Ported and polished head, fuel pump upgrades, Fast road cam, high flow fuel injector.

Stage 3 mods: Adding or upgrading forced induction (turbo/supercharger), Sports gearbox, Internal engine upgrades (pistons/head/valves), Competition cam, Engine balancing.

You need to keep as much low end torque as you can and aim to achieve a wide power band rather than a narrow top end power spike.

The point of our guides is to give a starting base of modifying mods and point you in the right direction, our forum is the place to go for detailed advice and tips on your modified car project, the best uprated mods and all aspects of modding cars.One of the biggest mechanical motorsport modifications you can do on your NASP engine is to fit a fast road camshaft .

The exhaust & intake durations play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car difficult to drive in traffic. You'd need to follow a camshaft upgrade with other mods and finish with a reflashed ECU to fully realise your gains.

You will need to ensure that the engine is not starved of fuel so will need to uprate the fuelling.

If you find you suffer from flat spots and surges after your modified parts you should check the fuelling and try a higher octane fuel as well. Larger injectors will enable you to supply sufficient fuel to the engine.

A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this if your injectors are demanding more fuel.

Volkswagen Tiguan intake and exhaust modifications.

Breathing mods are usually next up. Air induction kits only help to increase power if the air intake is restricted!

Adding an induction kit to most low power engines will see LITTLE LOW END POWER GAIN AT ALL.

If you have heavily modified your engine and it's need for air INCREASES DRAMATICALLY then an induction kit is the answer and will help remove this restriction.

Derestricting the airflow into the engine is the primary part of car tuners so get a better flowing air filter if you find that the car is running lean. Induction kits can sound fun but due to the warm air in the engine bay they will not add noticeable power and often rob you of power.

Sports exhausts will certainly help air flow out of the engine but avoid an exhaust that is too wide or you could will reduce the flow rate. Stick to 1.5 to 2.5 inches as a rule of thumb.

Getting the cylinder head gas flowed will help get more air into each cylinder. This is definitely a job for a pro with a flow bench. When you start tuning your Tiguan you will discover that the standard clutch starts to slip so get an uprated clutch. The best mods that we recommend for your Tiguan are Remapping or piggy back ecu, fast road cam and air intake and exhaust.

Turbo engines are just begging to be flashed. You will see big power gains on most modern turbo charged cars including diesels making a remap one of the most cost effective and big modifications for your money.The most significant power gains for NASP engines usually involve the addition of forced induction. Turbos are generally harder to add than a supercharger. Turbos increase power in increasing proportion to th engine speed and this can make mapping difficult.

It is more straightforward to map a supercharger because the boost is proportional to engine speed on a linear curve. Alternatively you could add water injection to control knock.

Volkswagen Tiguan Wheel modifications.

The benefits of alloys include reducing your unsprung weight and better brake cooling via the extra air flow they allow. Pay attention to your choice of tyres (tires) for your car, a good soft compound tire can really enhance your cars handling. The downside to large rims on your Tiguan is that you're changing your effective final drive ratio and this will have a detrimental effect on performance.

Although some people have fitted larger wheels we would stick to a 18 inch rim size as the maximum. 19's may look very cool but they really ruin the ride of the Tiguan in our opinion.
