Replaced the 1.5 year old Coolant reservoir cap back with the OEM version in hopes to stop the slow leak I think takes places from bubbling over. Also swapped put in a new MAP sensor in efforts to fix the boost surging issue.


Although I'm becoming more cynical in my hopes of chasing down the culprit, this is interesting because on the new MAP sensor there is an extra electrical rod sticking out the hole that you can see in photo 1 and photo 2 (of my old sensor) just to the right of the middle of the sensor. Well that rod is obviously missing on my sensor. So maybe this part will be the secret to whats going on
