Can you post a log? Was the car running before v3 was put in? Have you done a blt. Check engine light?

i actully cant post a log as my dumb laptop battery is junk and has to stay plugged in so stupid but it has a coolant temp sensor code and a knock sensor code thats it and i didnt do a blt but it has just under 20 vacum

A bad coolant temp sensor will make your car run bad. Look here http://www.dsmtuners.com/forums/newbie-forum/150208-coolant-temp-sensor.html

Try running an extension cord out to the car to plug your laptop into. What vacuum you have doesn't mean you don't have any boost leaks. Do a proper blt and check with soapy water.

Change the coolant temp sensor first and see where that gets you. That sensor plays an instrumental role in telling the ecu when to switch between open/closed loop mode. What are you knock settings in Link? are you seeing any knock while running. A log would help tremendously.

Since you already replaced the cts. Check for power on the wires see if you have power coming in and power coming back out and how far you have power. Maybe a broken wire somewhere along the lines

Is this a new build or was it running before link? What's your fuel pressure set at? Like stated above we really need to see a log. Right now there is a million possibilities. We need more info on the car.

This is a new build and ill have to check that cts wiring but would that really make it run like crap i know would give a hard start

The stock fuel map is super rich. If you look at the fuel trims, you can see that the ecu adds fuel threw out the rpm range, making it really rich in the upper RPM range.

Yes. Not saying that is your only problem but it's adding to it. Fix that, do a blt pre turbo and then find a way to get us a log.
