Ok I posted about how the service was great but here is the diagnosis, and the work that was done. I only had them diagnose cause i want to do the work myself.

First Issue - Car bucks under hard acceleration. -
The tech determined that since I have aftermarket taliaferro intake, and a stock ecu and exhaust, that the air input into the car is more than the air it can pump out causing the buck. does this sound accurate. Is this a good excuse for me to upgrade the exhaust and chip..

Second Issue - Car Groans/Hoots at 2900rpms. -
The tech determined that this is being caused by compressor surge. Im kind of confused as to what it was but he said that the two fan bearings in the turbo could be loose causing fast spool up but since the air going is is more than it can pump out its causing the fan to vibrate. He also said that finding a Viggen Boost control might help. My fried Chad who posts on the 9000 board seems to think it is a hooter valve problem and that a forge BPV will solve the problem. Any Suggestions

3rd Issue - There is a leak in the flex pipe. Is this a big deal or should I wait till i can afford to upgrade the whole exhaust.

4th - Bad Temp Sensor - They say 100$ fix but I assume i could do it for a lot cheaper. any tips?

5th - I got them to chang the Tech options to shut off extra wiper swipe, open all locks unlock at same time, but they said the could't figure out how to get the shift light off without talking the bulb out.

Sorry to make a huge post but you guys always have good answers.
Thanks in advance
