Need help diagnosing

[boostaddix]

First off id like to start by saying im newer to DSMs and ive had my 2g talon for about a year now, I bought it in mind that i would want to put in a 6 bolt to avoid crank walk, thus havent really kept up on maitance... The whole point to this thred is to find out why my 7 bolt is preigniting (or whatever els it might be) the reason i think it is pre firing is because anytime i go over about quarter throttle it sputters and looses all power. It acted like this once befor when i changed my plugs and incorectally gaped them. But with this issue i have used 3 diffrent kinds of plugs and played with the gap.
In trying to figure out the problem i have replaced knock sensor, and hooked it up the a scaner and took it for a drive. The scanner said it only retards 4 degrees or somthing and was told that it needed to be alot more than that..
i have also looked over my ecu and all the capasitors look good.
Now here comes the wierd part.. if i Regap my plugs and clear the ecu it changes how bad and when this happens, in a couple instances fixed it completly but on the next start up its back to square one... im lost any ideas??

what kinda plugs have you put in? what type of fuel are you running?

So If I'm correct your experiencing misfire right?

Ya what I believe is misfire but only past quarter throttle and ngk plugs

what have you gapped your plugs too? what is the condition of your wires? when you have been changing out your plugs what have they looked liked? running really rich? lean?

ngk 7s and .28 i think it might be boost leak from throttle body?? its a small leak.. cant imagine that that small of leak would cause this big of problem.. running really rich tho
