OK so heres the deal, bought my car in october, turbo went out in less than 400 miles so I opted for the KO4 upgrade and got 386cc Bosch injectors and Revo software. after being without my car for over a month, i got a check engine light 15 miles after leaving the mechanic. the car is running 23% rich. i downloaded the revo software on their website as well as lemmiwinks software. anyone have any other ways to lean my mix back out? parts, tune settings ect...

any input is much appreciated
