Late Post - Finally got the delivery of Virtus GTLine, Let's talk upgrades!

After months of discussion, research and waiting. Thanks to few inputs from this group, I Finally got my hands on a Virtus 1.0 GTLine AT. Did a quick short trip within a week to Mysuru from Bengaluru. So clocked 500 already and here's my quick review and Need for upgrades. Pros: 1. The TC+1.0 combo is heavenly. So smooth but quick whenever you need it. 2. Mileage is sub 10 kmpl within Bengaluru and 15 kmpl (manual mode; 80-100 due to traffic) and 17 kmpl (cruise control at 100) on the expressway. This number will only go up after a few services. So impressed. Cons: 1. So apparently there is some sort of TPMS but doesn't show values and only deviation in pressure. Like dealer kept it at 42 and as recommended on manual I made it 33, so started getting a warning about pressure loss. Had to reset it. 2. Info touch screen gets hot after few hours. So had to reduce brightness to lighten the load 3. Light sensor is super sensitive, every time I go under a flyover it starts throwing warning. 4. Car app is a dud. Have already added 70mai dashcam (proper wiring but not hotwired). After hours of self discussion, decided not to give it any coat but will apply wax polish at home every month or so. Would like to know if anybody in this community knows some simple upgrades to improve the overall working of the car. Maybe airflow filters, spark plugs etc.
