A newbie member although I have been reading threads for some months. Been a FIAT fan for decades - Punto (Mk I) x 1; Marea (Mk I) x 2; Tipo (Mk I) x 1; Doblo (Mk I & II) x 4; now Qubo (Mk II). Qubo is the 94/95 HP diesel (Trekking) and this variant is as hen's teeth. I had to go 160 miles for a sensibly (5 and a bit YO) priced one. The previous owner had, shall we say, been economical with fuel. Cheapest supermarket I suspect. After about 10 tanks of Shell V-Power, and new air & fuel filters, it started to more feel like the car I'd left behind as too old (Mazda 2 Mk I 2005; 67HP) but which was still punchy - rebadged Ford engineering as to when the turbo kicks in. The Qubo now responds like my last Doblo which had the 135HP 2L JTD. That performs/ed best in 3rd with a firm right foot; ideal for overtaking but still not as punchy as was the Mazda. I may chip the Qubo (take 95HP -> 115; from extremengineeringsrl.com in Italy). Been looking at the threads relating to removing the air-filter box as the chip wiring needs to be plugged in underneath. But then I stand back & do the 'big picture'. Does it make sense to chip this 1.3 JTD ? What experience does anybody have ?
