GM Crate Motor and GM performance ECU Tuning, LS3 480hp
I've installed a GM LS3 480hp with a GM performance stand alone ECU in a 2003 Porsche C4S 911, I need to do some tuning and change idle rpm and fan temp on/off. I've talked to Diablo, they make nothing to support the GM Performance stuff, I guess cause you don't have a vin number to lock it. Is this going to be a problem with ALL the Tuners? Wish I knew this ahead of time. Any ideas on what I need to get to be able to tune this beast?

All the ones I tuned in person I used efi live but I have tuned 2 through email with hpt also so I know they support it also. I heard there are some that are locked depending on package you bought but I personally have not seen one. There are a good number of GM packages out there so I know I have not came across all of them. They have changed a few minor things in them as the years went by. I have not seen one that has been bought in the last few months so I don't know if they made in changes that recently or not.
