My 2014 Audi Q5 3.0t is stock and my daily driver.
86,000 miles. Trying to keep as a sleeper. I do not want a noisy vehicle or attracting attention from cops or anything.
A APR dealer near me says I should go stage 2, with dual pulleys.
Is it a bad idea as far as drivetrain or engine longevity to do dual pulley and stage 2,
WITHOUT: 1. a upgraded or additional heat exchanger?
2. Does it really need a cold air intake? Or am I waiting my money with the stage 2 and dual or single pulley upgrade?
If I do buy a cold air intake which are a waste of money and what is the smart buy?
3. Keep stock exhaust?
Dual pulley vs a single pulley upgrade pluses and minuses?
Should I also change the transmission fluid?
What else should I know? Or think about?
Thank you!

 

Go to APR's website and see how much extra power you get with Stage 2 compared with Stage 1. With my 2013 A3,you get less than 10 additional hp for the cost of the downpipe needed for Stage 2. On the advice of my local APR dealer,I went with Stage 1 tuning combined with a performance air filter and cat-back exhaust. Hp 200 to 250,tq 207 to 312. And with a turbo motor,the turbos and cats provide plenty of silencing.
