microtech issues in altitude colorado
 

i just brought my car from FL to CO and is running like shit no boost at all. i already check all clamps for boost leaks etc etc.i guess the altitude has something to do. im 4700 feet above sea level.

Um, OK. Is it rich? Lean?

Off hand, I don't know if the Microtech does altitude compensation. It would surprise me if it does since even in London Ontario vs. Australia, my Microtech reads 2" of vacuum at atmospheric.

the map sensor should auto compensate. i drive at various altitudes for hundreds/thousands of miles on a single trip and have no issues.

the car probably developed a boost issue that is coincidental. wastegate could be stuck, boost controller faulty in failsafe mode or boost leaks(i don't trust that someone just sais they have no boost leaks without saying how they tested the system or how thoroughly, the ONLY way to accurately test for leaks is by pressurizing the system).

it is rich

car is fixed it was a clogged injectors.

I was going to say.. I drive mine from Fl to N C mountains every year w/ no problems running the LT8S. Glad you found the problem and didnt run lean. G
