AUDI A6 2.7 TWIN TURBO D2 System HELP

[davidmano1]

WANT TO DO A D2 SYSTEM BUT CANT ADJUST THE A/F RATIO BECAUSE OF THE GIAC CHIP THAT IS INSTALLED. I NEED A 12:1 RATIO BUT CAN NOT DO IT WITH THE CHIP. NEED HELP WITH THE SET-UP. CALL ME OR EMAIL ME AT 1-215-361-0117 EXT 4105 dmano@keystonemotors.com

ps: the chip sets the timimg and the fuel curve, if I adjust the fuel pressure lower to lean out the fuel curve that still leaves me with a timing problem. I can't adjust the timing. I need a custom chip to set all the perameters. Unless someone has a better idea.
