Hi all just bought an s4 and it seems to have a problem.
The car has an big power surge up to about 3500rpm then holds back and then at about 4500rpm seems to kick back in again, its not a massive loss of power but its well noticable.The car has done 113000 miles and ive just had the ecu remaped ive changed my diverter valves and changed to silicon hoses, well to the top of the intercoolers that is .
Please help
