why do you want your car to overfuel? it wont add power, it will cost you more in petrol and it will wear out components quicker

bit of a childish reason as unburnt fuel means flames out the exhaust! stupid i know but wanted to see what its like but will mostly change it back so it wont overfuel after a day!

unplug your coolant or air temperature sensor. that should make it overfuel

If you want a J cam get the 1.6 xsi head, its identical to the rallye s1/s2. The Z cam in the xsi 1.4 isnt too different so I'd just keep that to be honest. You'll need the rallye injectors as VTR ones dont fit too well. With a 3.5 bar as in a VTR it was overfuelling so I put in a 3 bar one, it still pops and what not and thats with with a cat in place and unsilenced mid pipe
