Hi the car is a 2003 cobra with a 2.80 pulley, kn fipk, off road x pipe, and flomaster catback. The car is detonating at wot every time i go from 2nd to third. I data logged it and the timing was around 20* so I took 5% with the predator (u7142) but still no luck. Oh this is on the 93 octane performance pulley tune.

Try a larger change to see if it helps, like 10%

Check you fuel pressure at the rails to make sure your filter isn't clogged, what kind of miles are on the fillter?
If your retarding timing and adding that much fuel and it's still detonating it could be something your not considering..
