hello
I have a fiat panda 1,3 also.

i think my panda has a lower consumtion of diesel after my chip tuning(not novitec)
My biggest problem is the clutch after mounting the diesel box and turned it up a bit. the clutch slips quite badly from 2500rpm up to around 3300rpm.
when switched back to standard i cant even get it to slip....
im curently saving up to get a custum build clutch that will handel around 120hp and 250nm.. not that i got that kind of power but ... you know I WANT MORREEEEE!!
it goes around 5.3L with a constand speed of 135km/h spedo(on standard 13" rims)
16 inch rims are coming home from USA, novitec exhaust and 40mm lowering is in house...
but the exhaust does not seem to fit my larger standard exhaust?????
novitec.dk says that its the same size????
