LS Transplant EFI help

[hotrodstingray]

On the fence choosing a EFI transplant kit for my 67 Corvette, installing a 2008 LS7 with West Coast Cylinder's stage II heads, comp cam Dur @ .050 281 289 112 Lobe Sep & 650 lift, LSX FAST intake and 1023 TB. Close ratio magnum T56. Choosing between FAST EZ-EFI, Terminator LS MPFI Kit or flashing the original computer. Would like suggestion or experience with EFI transplant systems. Building mainly a street car and occasionally auto crossing.

If it were me, I'd use the factory computer.

There are lots of tuners out there that are very experienced and very good with the factory ECUs. Finding a tuner for an aftermarket system is quite another thing.

Agree with above, I used factory computer on supercharged LS7 and the BEST tuner in my area.

Cheers

Thanks for the replies.

Are you going to want to make changes to the tune yourself in the future? What do your local tuners use/prefer? Stock ECU is great, but not as user friendly as some of the aftermarket options. And if you are going to rely on someone else making every change to your calibration, you might as well use what they are most comfortable with.
