Fahvergnugen Tuning
I specialise in re-mapped performance chips for standard and modified Polo's, with very noticable performance improvements. Fahrvergnugen chips run in everything from stock 1.0l to rallye and drag race cars. I mainly focus on the cars the bigger tuning companies ignore or charge 10 x the amount to even consider looking at!
My standard generic chips do not effect your cars original reliability and mapped to ensure optimum performance without risking excessive stress on your engine.
If you have any questions I am always happy to help.
International orders welcome, I offer very resonable postage rates.
If your car model is not listed below please PM me, or start a new topic. On NA cars typical power gains are between 3-10% depending on engines level of tune. In many applications when driving steady you will notice an improvement in fuel consumption, obviously when driven hard fuel consumption will increase.

The improvement in the mid range drop is very noticable on the road and I would strongly recomend my 16v chip for this reason alone.

A gain of around 11.5Bhp, however due to differences in vehicles expect around 6-8bhp. The graphs also show a max increase of 14Nm or torque, again this may be less in some applications, taking peak torque above a stock G40! (150Nm) to 159Nm.

I am constantly expanding my range of chips for other models.
For more information please post a new topic with vehicle model and engine details in the topic. I can supply remapped chips for most popular european cars not just VAG.
I will require engine CC and ECU numbers, to check compatability.
Paypal payment preferred.
