Is that victor JR ported at all? Massaged anywhere? If that thing is literally pulled out of the box and bolted on... there is 75% of your problem. That intake was designed to be ported. I cant tell you how many times ive seen it lose power over Fast intakes. You really have to have a good idea of CFM flow throughout the entire motor to use that intake. Get that car on a dyno and see what its doing.

Should be well into the 10.30s then with a stock bottom end LQ9..?
Nice passes Cwarta, personally I thinks it's the 243s holding it back... Look for some 1.875" headers too!

I'd be willing to bet the house on your tune being screwy.
Can you post any excel sheet data logs, with actual AFR, timing, etc..?
My GTO with just longtubes and a tune ran 12.17 @ 115... there's something up somewhere on your setup.
