I bought a used 2017 Volkswagen Polo 1.2 MPI Highline Cup Edition from Spinny and really enjoy driving it. However, the engine feels underpowered while overtaking and on uphill stretches. I know the 1.2 MPI does not respond dramatically to tuning, but I have seen several videos on tuning MPI engines, and none clearly explain the exact power and torque gains. There are also mixed opinions online about different tuners. I am looking for a decent 10hp increase with minimal changes to the engine and definitely do not want pops and bangs. Could you suggest a good tuner in Bengaluru for the 1.2 MPI for this requirement? Also, is it always recommended to get a Volkswagen serviced at an authorised service centre, or are independent workshops a better option? Could you suggest some good service centres in Bengaluru for a Volkswagen Polo?

You are absolutely right that the 1.2 MPI is not an engine that responds dramatically to tuning. It is a naturally aspirated unit with limited headroom, so expecting a meaningful +10bhp gain with minimal changes is unrealistic. A remap can sharpen throttle response and marginally improve drivability, but the actual power and torque gains will be modest at best. Most reputable tuners will be honest about this, and the divisive opinions online are often a result of unrealistic expectations rather than poor tuning.
In Bengaluru, we do not have any experience with a tuner we can recommend, but suggest you look at the more established names with experience on VW MPI engines. They focus on sensible, reliability-first remaps rather than headline-grabbing numbers. However, even with the best tuner, the gains will be incremental rather than transformative.
On servicing, Volkswagen authorised service centres are the safest bet for a 2017 Polo, especially if you want to maintain the car well and avoid any ambiguity with parts or procedures. That said, there are a few independent VW specialists in Bengaluru who are well regarded, such as Car Smith Motors and VAG Tune. They can often offer more personalised attention and a better understanding of older VW cars, but it is important to check their reputation and experience with the Polo specifically.
Overall, enjoy the Polo for what it is: a well-built, fun-to-drive hatchback. Keep your expectations realistic with tuning. If you want a significant performance increase, moving to a turbocharged car is the more effective solution.

Since Toyota Hyryder Strong Hybrid does not come with a spare tire, I want to get it myself. But the problem is that although the Toyota dealerships in the entire region have the requisite stand available, the bolts required to fasten the stand with the chassis underbody are nowhere available as the manufacturer is not supplying the same for about last two months. How do I resolve it?

The lack of bolts appears to be a parts availability issue rather than a reason to abandon the spare wheel conversion. However, the mounting hardware for a spare wheel carrier is a safety critical component, so generic bolts should not be used simply because they fit the threads. The correct bolt size, thread pitch, length, strength grade and washer arrangement need to match Toyota's specified hardware.The best approach is to ask the dealer to raise a formal parts request with Toyota and escalate it through Toyota customer care. The dealer should also check whether the same spare wheel carrier and mounting hardware is used on the non hybrid Hyryder or the Maruti Suzuki Grand Vitara, and whether the required hardware can be sourced through that parts network. This should be confirmed by Toyota before anything is fitted.A reputable fastener specialist can be used if Toyota provides the exact part specification, but there is little benefit in guessing the specification yourself. Avoid drilling or modifying the underbody to accommodate alternative hardware.
