Default Ran my z28 with hci and built motor

Went to ATCO last night. Did not beat my personal best 11.7 at 116, My car had an off day. 2002 camaro z28 built 347 with z06 rods, custom pistons, ls6 aluminum block. Ls6 ported heads, 236 duration cam. Ls6 intake, slp maf, slp ram air, ported TB, Performabuilt level1 4l60, vigilante 3600 triple disk converter, strange 12 bolt with 410's. Qa1 coilovers, Bmr and spohn suspension. Here are my times. I was playing with the psi on the new 265/40r18 et streets. 19 psi seamed to be the best. First run was 25psi. Second was 22psi then 20 last 3 were 19psi but the last run i did not flash the converter right.
Run 1 60ft 2.246, et 12.525 mph 115.84
Run 2. 60ft 1.923 et 12.157 mph 115.24
Run 3. 60ft 1.875 et 11.945 mph 115.30
Run 4. 60ft 1.724 et 11.975 mph 114.67
Run 5. 60ft 1.724 et 11.934 mph 115.10

Yes dyno tuned. 380 hp and 340 tq on a mustang dyno. I think the ls6 intake and the tb are choking it. I have trapped 117 in the past.

I would of thought you would be more mph with the ported 243 heads. I have trapped 120 on 241 heads. Just seemed low for a DA of 300. Either way if you get the 60' lower you should be easy 11.5s.

Does your car weigh 4000lb+?
You really need to weigh that thing. I would expect a lot more out of your mods but knowing the weight is a important piece of info.
I'm not trying to be a dick but all the #s seem low even for a ls6intake.

Who ported the heads? Maybe the tranny needs adjustment? My old car with AI ported heads and cam, stock 10 bolt, 4.10 gears ran a 12.1 at 118, with a 1.9 60. Yours should be better than that.

Found out that when I installed the ram air, I pushed the hoses back into the pulley. It was rubbing on my radiator hose and ac hose and put holes in both. I fixed it and have a track rental Thursday if it doesn't rain. I am going to have my tuner check the converter and make sure it's locking.

Good numbers, there's more in it.

I was not a fan of PI converters in the past, are they better? His lost mph could be (based on my past experience) eaten up by his converter.

As far as the ET goes, I'd be looking at shift points too.

You guys were right. Something was wrong with my car. The converter was not locking. They fixed it and I'm hoping to go to the track tomorrow
