I've posted a thread similar to this for fuel mileage but now I just want some more torque. 1997 Ford F-250 XL HD, 7.5/460, 4X4, E4OD automatic transmission. Everything is bone stock on this truck. There is no exhaust system after the cat converter, thinking about putting a stack or a straight pipe. But if I could get some suggestions how I can gain some more torque for a low price, that would be great. Thanks.
