hi folks
my girlfriend had her 94 wrx on a rolling road day at the weekend just to see what it makes but all didnt go to plan.
the chaps had to abort the run as it is running to lean.
the graph they gave her shows the boost rising to 12psi and the mixture follows the same path.
is this going to be a simple fix or or lots of money??
the car is standard apart from a 3in exhaust from the front cat.
any help or advice would be grateful
thanks
