The harder you go on the accelerator, the engine sounds all the more sweet and you start moving faster. The engine note improves and the feeling of driving a petrol car seems to déjà vu through one’s mind. In the third gear the car seems to be wanting to take off and the in gear acceleration times tumble by a significant margin. The car does not seem obviously different through the first two gears and then the change is evident. Once the engine is cranked there seems to be a slight change in the engine note. So now, with the tuning box in place, how does the car feel? Lets find out. The ECU scans will however pick up ECU remaps, which is not the case here. This is because the tuning box is not picked up by the ECU scan.

Whenever your car goes for service, you can simply unplug the box and send the car for service in its original condition, the service guys will not have the slightest idea that your car was running the performance box. No car manufacturer will support it though, and they normally have a tendency to void the existing warranty on vehicles running performance modifications but there is nothing to fear. The box has been tested for thousands of kilometres before being launched into the market by Petes Performance. Hence we are able to extract 90bhp of power and 215Nm of torque from the original 75bhp and 190Nm, neat isn’t it!! Needless to mention that the tuning box is absolutely safe for your car. The tuning box enhances power by changing the engine map settings. The engine cover has to be removed for the installation though. Installation is easy and it does not take more than about ten minutes. Go back to step one and you should be fine the second time. If the engine checklight flashes on the instrument panel after fitting the box, then there is something wrong and you probably haven’t installed it correctly. Once this is done, just tape up the box in a secure area in the engine compartment and you are ready to go.

All you have to do is to connect the pin (of the box) into the injector and the one from the injector into the tuning box. The Pete’s Tuning Box is actually a very simple device. Petes Performance send us the Digital Diesel Tuning box for the 1.3 Multijet and the Fiat Grande Punto was ready to take on the Maruti Swift one on one. When one compares the two cars, the Grande Punto is a wee bit sluggish when compared to the Swift and that is mainly attributed to the fact that the Punto is heavier and has taller gear ratios. The Fiat Grande Punto is pretty well built and outshines most of the competition but the toughest competition comes from the Maruti Swift, which shares the same 1.3 Multijet diesel engine.
