the only breathing mods done since the uprev is the ducting i created to get more air to the filters. the cooler was the last actual part installed though. but now that you mention fuel map the car does bog slightly every once in a while when going into first gear. thought it might just be my error though. the oil however is spot on right in the middle of the dipstick so i dont think thats the issue. i just dont have the money to take it back to uprev right now
