well i have 245/45-17 and i am running 4.10s although i had to get a sct flash tunner, i like it but now i finish at the strip in 4th gear instead of 3rd like with the 3.55s. it has so much pull in 5th its crazy.
i have bbk long tubes with prochamber pipe with a sct tuner and it was a good combo, i went with 4.10s they wrap out so fast it was a good move for me, i think if u get a blower you should get 3.73s
id like to see you run a 13.19 at 105 stock, research before you lie. since only some of the best drivers ran around 13.7s when motor trend tested it to gto
