Max timing with the spout out with a churbocharger

[OrangeMustangGt]

Whell guys, i've been getting a really annying bucking when cruising below 2,000 rpm...much more when the engine is been running for 30min or so.. I was told it could be that my computer is adding a whole ton of timing under light load.....SO, i was thinking that i could lock out my timing? However, how much should i go? would 15 btdc be ok? What do you guys think with my combo....gt40p's/crane 2031 cam/explorer intake.....10lbs of boost.

Also, just to pick your brain, is there anything else that could cause this? I gapped my plugs real low, at .025.....could that be an issue? Btw, new plugs, wires, coil, etc. How about my coolant temp sensor?....

i had the same problem wiyhout the churbocharger lol. turned out to be my new MSD coil...look at coil in the dark for a glowing spark mine was grounding out on the backside and i could see the spark in the dark. and i would also open the gap to .35 and see what that does...
