I would use super unleaded personly as its the best fuel to use. I always fill up with shells Optimax as its the best around, like I say personly only as its cleaner and gives you better performance. But the cost isn't good not cheap, all depends on what you can afford
Anybody know the difference between Squadra chips and Autodelta chips ?? What have most people used ?
I have been running my 145 Clover since March with a Squadra chip from AO. The only difficulty was getting the flipping carpet up in the passenger footwell :-)
Performance wise .... more torquey low down the rev range. I have also spoilt it with Shell Optimax ... hence I have dozens od those silly trump cards .... hey I may win a 50 grand car yet.
If anyone wants the original chip from my 1999 145 it is sitting here on the shelf !!
