I am new on this site and new as a vette owner also. I have a 2015 ordered with allocation and confirmation number. Dealer called today and said order will be firmed up in two weeks. with this going faster than I had expected I haven't got the info I need from others about the Lingenfelter options available that I may pursue. I spoke with them recently and they said they are waiting on parts for the magnuson supercharger and the fuel pump required to run the system that I'm thinking of going with.I'm thinking of going with the 417 and the magnuson. I would like to hear what others have done with them or if anyone has a c7 ran through there shop all ready. When I spoke with Tim the other day there I didn't get the feeling they had done very many yet. His numbers for horsepower and 1/4 mile times were in progress yet. They were very eager to get it in though. I would like to hear if anyone has any stories or info. Your help will be appreciated.
