check engine light


The problem is my check engine light keeps coming on and the trouble codes it throws are
P1000 - OBD system
P0305 - knock 1 if i remember right
P0325 - knock 2 if I'm right
P0330 - #5 misfire
P0174 - system lean (sometimes)
the car is a 2001 cobra with a DSS level 10 stroker motor with bigger throttle body, under drive pulleys, 4v heads, sct tuner.
The question i can not figure out is why i keep getting knock 1 & 2 if the knock sensors are turned off with custom tune . I have checked plugs look fine. i have had a couple people say its the computer about ready to go or try running higher than93 octane gas. Did not have these problems until stroker was put in. Before had stock cobra motor with same mods and no issues. Any help would be great. thanks.

Jason
