PIRANHA PERFORMANCE

1. Get a off the shelf chip which currently is the 2nd best option, but will not get the max out of your engine and you will not be fine tune the chip to various engine modifications and, most importantly: Malta's hot humid weather and low quality fuels. I have heard countless stories of people getting big name chips installed and engine being over fuelled, having a rough idle, rough acceleration or being very smokey (even petrol engines)... 2. Fit a tuning box. Now this is a scam... How many tuning boxes have you opened? All you see is a (usually) black substance covering all the "magic circuitry" I've pulled apart a few tuning boxes (taken off client's cars), in most cases all the box contained was a simple variable resister. This resister changes the signal from the fuel temperature sensor which tricks the ECU in thinking that fuel is cooler than it actually is, so that the diesel pump advance the pump timing, increasing diesel.
