SAFC setting for 780 on a 550 chip

[shadowdrag]

I will be getting dsmchip for 780cc in about 3 weeks but just need a starting point to start tuning on a 550cc dsmchip. I am assuming when we have stock 450 and upgraded to 550's the average SAFC setting is around HI -17 when in full boost, therefore my 780 is about 200cc larger than a 550 chip, so I should start it at Hi-21 when full boost.

Does anyone have a similar set up that can help me out? Haven't took it out yet.

Thanks

Why not pay $20 to send it back and have new settings "burned" to it?
