I know you have a tuner doing your tuning for you, but I'd love to see what the timing map looks like. You could probably cut a 1.4-1.5 60' with the same 5psi launch if it had more timing in it down low, while still keeping 16* in at @14psi up top.
OR you could just throw the kitchen sink at it off the line and put it on the bumper.
Honestly, if the timing is as low as it probably is at the RPM you launch off the brake....you could probably launch with all 14psi you're running now.

It takes a while on the tbrake to build boost, I don't think the tranny would like me sitting there for a minute try to get it up to 14 psi lol. I need to get with my tuner about the timing and my rev limiter. It starts to nose over at 6400 through the exhaust, but open dp it's still pulling f*cking hard. Right now the rev limiter is at 6800, it needs to be 7200 or so.
The same thing can be said for a turbine wheel that is too small, a down pipe that is too small, exhaust that is too small OR too long etc. etc. etc.
Removing that restriction is going to allow you to make more power and run the engine up higher into the rpm range while still making power every single time.

what was teh 1/8 mile mph on that 144 pass. i run the same pt88 on 19psi and 15degrees on meth and went 9.25 at 153.3 with a 1.56. crank it up and let it eat that car should be a fun ride. i have been 116 in the 1/8 on 15psi/15 degrees on straight pump.

Very nice mph that's for sure. I remember a HUGE debate a few weeks/month ago where I was told it was worth nothing to run an open DP on a street car and that it was "unnecessary" because Mighty Mouse didn't pick up anything when he dropped his. Well I guess gaining 11mph is just blah and "unnecessary".
When I tell people things, it's not just to make their life harder or argue it's because it's the damn truth.
Very nice shake down runs that is for sure.

If it was 3.5 all the way back with straight flow through mufflers it wouldnt have amounted to much of any gain.
What kind of muffler is on the 3 inch catback on this car?

So basically a straight through resonator?
If it was a full 3.5 or dual 3 inch or even a single 4 inch system all the way back it wouldn't hurt much at all like that single 3 inch system. Usually easier to just run a cutout on the dp and leave your current setup alone.
I personally like to run a full quite exhaust that flows enough with the car on kill mode and not have to uncork anything or lose power because the full exhaust.

I take it you've tested this yourself?
Have you ever seen a 2otl muffler? It is far from a straight through resonator, it's a chambered "box shaped" muffler.

You keep thinking that. Mighty Mouse ran a full cat-back on his car, and the argument was when he dropped his cat-back and went to 3.5" dp it gained nothing. Same apples to apples comparison as this case. MM's problem was backpressure before the turbine not after it.

Dude not worth it. He enjoys swinging from nuts since no personal experience

Straight thru and short as posible is the most ideal but sometimes that can't happen due to some things like aesthetics or just personal preference.

Here is a video of my 10.58 pass with a 1.96 60ft leaving on maybe 1 psi

Just watching how soft the car is now, if you could get it to leave on 12-14psi and ramp it up to 20-22psi as quick as possible, it will go 8's no doubt.

When that thing comes on line, it comes on like a beast! I'm super excited to see how those LSA heads do when you really start cranking on this thing.
