Tiguan Tuning

"Easy Tiger"

The Tiguan is unusually placed as a fun family oriented SUV. 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 popular among our members for their car tuning projects. Improving the cornering and general handling of your Tiguan should be high up on your priority list. To improve the handling you are generally looking at suspension and tyre upgrades and larger drops are not always good, as it can impair the ride quality.

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!

When Tiguan engine mods are being done you have to be careful to keep the power band as wide as possible, the wrong mods will just raise the power band leaving a torque shy bottom end.

Keep the car looking standard and remove the badges for the ultimate sleeper!

Smaller engines do not usually provide much of a return in terms of power so choose a model with a more powerful engine engine. You could always do an engine swap if you have a small engine to start with.

Volkswagen Tiguan Tuning modifications.

The following modifications are usually performed by our members, decide how far you want to go before you begin.

Getting the right mods for your planned usage of the car is vital. Stage 3 (competition) mods just don't work well on the road.

Stage 1 mods: Exhaust, Panel air filter, Remap, lighter flywheel

Stage 2 mods: Ported and polished head, Fast road cam, fuel injector & fuel pump upgrades,power clutch

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

Bear in mind the mantra that you want to keep as much low end power as you can and aim for a wide power band rather than a narrow top end power spike. Whilst a lot of car part makers will claim peak BHP figures what you really need is a dyno plot showing the full torque curve.

One of the most significant with the best cost to power gain, engine mods you can do is to fit a fast road cam. If your car is making more power then it will need more air and fuel so fueling upgrades are important mods if you are serious about power.Just getting larger capacity injectors will go a long way in ensuring you deliver sufficient fuel.

Volkswagen Tiguan intake and exhaust modifications.

Before you start doing engine mods you have to get the breathing right and remove any restrictions in the system that could inhibit air flow.The cone filters or 'Induction kits' work well on turbo engines and larger engines (providing they are fitted with a suitable cold air feed or air box), for the smaller Tiguan engines you should go with a sports panel air filter made from a high flowing medium. When it comes to exhaust the key thing is flow rate. Big exhausts do not always flow better so don't go sticking on the biggest pipe you can buy!See our article on performance exhausts for details of the issue around large bore exhausts and how to choose the right size for your engine.

Airflow through the head can be dramatically increased with some professional porting and polishing. These should match and be setup to take into account any other engine mods. A good fast road power clutch will help to keep that power going where it should. Never just hope that a standard worn clutch will cope. Remaps offer significant power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a remap on a NASP engine will help unleash the potential if you have done a lot of mods. Despite the large cost involved adding forced induction to a NASP engine will give large power gains. It is easier to bolt on a supercharger than it is to get a turbo working. Turbos give boost in exponential proportion to increasing engine speed and this can make mapping difficult. The nice steady boost to rpm characteristics of the supercharger make them easier to map. Alternatively you could add water injection to control knock.

Volkswagen Tiguan Wheel modifications.

Alloy wheels will help the brakes cool down and are usually lighter than the steel ones. Large Tiguan alloy wheels can decrease performance. If you get big alloy wheels you will be changing your final drive ratio. For this reason we would advise sticking to a maximum wheel size of 19 inches, although we know some of our members have gone larger than this with no problems and we have to admit the TIguan looks great with really chunky wheels on it.
