Hi not sure if this is the right section to post this question.
New member and new owner of a 2005 wrx wagon.
When I bought the car a couple of weeks ago I new the car felt underpowered after previously owning a classic many years ago but new the car and engine were good. The car has prodrive exhaust, 18 " pro drive wheels, silicon y pipe etc so I assume it has the ppp.
Anyway after much invedtigation I found the source of the problem. There was no restrictor pill in the vac line, infact that part of the vac line has been replaced with a small red silicon piece.
So after further investigation i put a 1mm mig welding tip where the pill is supposed to go and voila power is back.
So I decided to check the ecu to make sure the car is mapped with the ppp map expecting to see a sticker on it. But there is no sticker yet there is some info wrote on it in marker pen. Ive attached some photos of the ecu. Can anyone identify what it might mean or if it is in fact what prodrive would of done.
Cheers in advance.
