Hesitation? Knocking Problem!!

Yup... me again... Getting a hestiation problem/ knocking on the highway. Thought it was spark plugs or coil packs. Havent changed the spark plugs yet but coil packs i did do. I thought the knock was occuring at high RPM, however, it seems to be occuring in 3rd, 4th, and fifth... at around or near 80-95 mph. Starts as a slight hesiation and builds to a hard knock. If I have my predator tune in it does it more then when its stock.. but stock it does still do it. The dealer reflashed the ECU and said go home basically we dont feel it ( seeing as though they wont push the car to 95). Well i dunno what to do , I think race fuel is going to be my next step and see if its timing related. ( If adding race fuel- 110 octane will stop the knock) I really do believe its some sensor somewhere. Just really wierd its at the same SPEED in every gear not RPM.. I dunno.. tranny speed sensor maybe. i dunnnooooo..........hit me up with suggestions.........
