You have too much air and the mixture is still burning when the exhasut valves open.
You need the pcm to retard timing a few degree in order to run more boost, dont go into wot for a few days and see if the pcm can learn the new boost values?

Give it the time and we'll see what settles in and what doesn't. Keep in mind my car did that too, but was probably mostly the fault of the ported TB with the Gen2 SC. The LIM was ported at the time.

It'* POSSIBLE the LIM porting won't work well with the Gen2 top end flow. You have to remember there was some risk in jumping on this.

Time will tell part of the story.

i just have a bad gut feeling for some reason
its like three extra or so pounds of boost is enough to do it.
