I had to call out Audi roadside assistance over the wknd after getting my car back from the garage and having a coolant issue after all the techs had finished at lunch.. Anyway, got chatting about remap's etc for my 170BE.. He mentioned you can change a resistor which changes the fuel fead and can increase power by 30BHP??? Ive not heard of this and thought if its true then you guys will have. He said he put one in his VW transporter work VAN... Any ideas?
