[Tuned55]

Hello

I've got a 55 Chevy BelAir with a 98 LS1with a T56. I sent out the ECM and had it programed. The car dose run fine for the most part but it dose have a few issues. I bought the EFILive scan tool, software, etc. a while back but my old lap top was, well, old. I bought a new one running Windows 7.

If there is a thread going over this I could not find it. I need help from the get go. Installation, registering etc. I have a 300 mile trip planned for this weekend and would like to see what's what with it.

My issue at the moment is EFILive will not install on this new lap top? I get this The requested operation requires elevation.Win32 error: 740

Thanks in advance
