The GIAC flash seemed to be the most important piece of the puzzle for my car... after all the other intake / exhaust / plenum modifications the GIAC programming tunes the car to make the most of the upgrades... I have a baseline dyno and will have the car dynoed again when I get it back from the shop...

my best baseline was 305.4 which works out to about 360.4 crank using 1.18 factor...

I expect crank to be over 400 with mods in my sig when I get next dyno completed...
