Hey all. So... I'm kind of scratching my head and wondering what direction I should go in next and I'm wondering what everyone else's experience and thoughts are. I've got all of the fun aftermarket bolt on go fast goodies, I'll list separately below. I've dipped into the 12's a few times in mindshaft weather conditions, but mostly been hovering around the low 13's for the last few years. The car is making most of its ET in the first couple hundred ft. I'm getting bored with the car. Is there anything I'm missing, and if not, what should I do next? I'm not sure I'm ready to dive in with heads and cam yet. I really want to be solid in the 12's and find some more MPH. On average, I'm running 13.20-13.30's at 100-101 mph. Keep in mind I want to keep the car somewhat streetable, but no where near a daily driver. Just wondering if there are any bolt-ons im missing or if there is something else simple. Will a dyno tune find much more? Will updating valve springs and adding high ratio rockers yield much? Any info or advice helps. Please don't reply with "did you do a search?".

CAI
LT's
3" exaust
3600 stall
3.73 gears
6al MSD
Solomn mail order tune
All of the usual deletes, Cat, EGR, Air pump
I'm sure I'm forgetting something...

Thanks in advance for your input.

Next logical step is Nitrous. I have a Nitrous Outlet plate kit and it's great!

Have an automatic 95 Z28, almost all stock with Lunati Voodoo 60122 cam, BBK throttle body, Pacesetter headers, 4.30 gears. With Hoosier Quick Time DOT slicks it ran 12.17. Did the tune with TunerCat. Forgot something, car had Nitrous and has larger injectors. I actually think they are too big without Nitrous. Ran 11.60 with Nitrous but I was thinking it would die if I didn't remove it. The bottom end is completely stock but I had to rebuild it because it lost a lifter and had metal everywhere. Had the valves done at that time, put used LS1 lifters in it. Using the stock Opti-Spark and ICM with a MSD 6AL and MSD Coil.

My only headache is the knock sensor. Put in a LT4 module and have it tuned to the highest number I can. It still retards the spark during the burnout. Should just tune it completely out. If I do anything to it I would be a set of better heads.
