I havent done it yet but planning to do it this weekend.
Please let me know if I made the wrong choice.
I would go with GIAC but the dealer(Autoscope?) is all the way in dallas and they are only open on weekdays. I work 9-5 and cant get out any earlier.
Istooks motorsport is right here in fort worth and they are willing to take me in on Saturday.
If autoscope is willing to work on my car Saturday I may just go with GIAC.
