Also put in a 94 Mustang GT T5 computer.  Cold Air Intake/Hpipe with no cats, ac/smog pump has been removed and all lines have been pluged.  No issues with the T5 swap.Problme: At WOT the car bucks/hesisates almost sounds like its bouncing off the ref limiter at 1500-2500 rpms. But runs great at 3000 and above.New plugs,wires,cap and rotor. New Fuel filter. Noticed the issue after putting on the cold air intakeI have tried to tune the timing. At stock timing 12-14 degrees the problem is bad.16-17 Degrees, it gets better but the car falls on its face and spark knocks bad.I pulled the spout when i did the timing. The check engine light is out on the car, and when i hook up and scanner the computer will to talk with the scanner. I am thinking either the tps or fuel?Also the car idles fine no surging or anything. But the idle hanges in between shifts. Any help would be great thank you</blockquote>
