Bigger picture is an understatement.
Turbotimers are rice, plan and simple. Drive the car out of boost for about 5 minutes on the way to your house/parking spot, let it sit for a few seconds and shut it off. All a turbo timer does is let a ricer come blasting in full spool into a parking spot and get out of the car and chase after some chicken heads.
Look at/take out an injector and read the serial number. Find out what injectors you have first off. Post a pic of the engine bay. Maybe you have a rising rate FPR or something sorta helping this get some extra fuel with boost. I would to a compression test too, becasue it this was un tuned and ran for xxx time stuntin around on boost who knows how well the motor is to start.
If anything, just dont boost it until you get it looked at properly.
