I just picked up an 05 gt. As far as I can tell and believe from the seller, it has ford racing intake and throttle body, roush Cai, different injectors and an engraved Bama placard in the engine bay. I assume it has a tune and the seller thinks he has the tuner at his other place for me. Fingers crossed. It runs perfect at 1/8 throttle. Pretty good 1/2 to full. But if I pull out quickly with 1/4 throttle it goes, bogs down for about a full second then then jumps. Or 1/4 throttle up a long hill it just won't accelerate until a bit more throttle is applied then goes good. Any ideas before I get the tuner and talk to Bama? I can track some info on the Torque app.
