I have a 2000 GT with a 2.1 KB kit on it with the following mods. The engine has be built for the KB with fully CNC heads and 274 comp cams. It has a 75mm TB and the SCT MAF ( not sure of the model number) along with 60 LBS injectors, new plugs with .030 gap. Aftermarket COP ( problem still there even with stock ones) bigger pump, Kb BAP, sct tuner, no cats, xpipe and I think I covered about most of it. All of the test are normal on the compression check and leak down.

The problem has a kinda like mist on accel but if you slowly hit the gas it does fine. WOT it doesnt act up and no check engine codes and its only related to cylinder 5. any suggestions?

Does it smell like fuel when it does it? Could possibly be an injector leak from a blown injector o ring. Any way you could get a video of it?

No, it doesn't but they are new injectors. I misunderstood the guy he said that cyn5 plug is clean as it can be like its a new plug. The rest are blackish but its almost like its a intermediate problem because he said it will do right and then act up later on while driving. Cant get a video cuz the car is at the tuners place. There isn't a intake gasket leak.
