I picked up a 97 cobra last year, then last fall I picked up a used KB 1.5 for it. It has a safe custom tune, kenne bell with 5/6 lb pully, 42 lb injectors, lightning maf, jlt cai, stock TB, stock exhaust except flowmasters welded in. But down 301 HP an 279 tq. I had to run it with out much cool down time. I got there about an hour before closing. Any guess what a o/r x pipe an larger tb might do?
