finally ran my car at the track, didn't do so well

Go watch an NHRA stock car run. They 60 like a banshee then die at 1000 ft. Just an example, you could 60 great but not make enough power to carry it out the back end. A faster 60 DOES NOT guarantee a better mph. Not sayin it can't happen, but it's not guaranteed.

I've trapped 145mph on drag strips with 1.5s 6fts
I've trapped 145mph on airfield with road tyres with 2.5s 60fts.
IMO the 60ft plays a small small role in trap speeds as you still have 1260ft left after that small distance with which to gain speed.
ET's now, that's a different matter of course.

Its pure physics, a good standing launch has a higher acceleration therefore higher chance of a higher trap speed assuming equal weather conditions and power vs. a terrible launch and slower acceleration. You literally have a longer distance with a higher acceleration giving you a higher trap speed.
A good launch will often yield a lower elapsed time, shorter time to achieve any trap speed. So often a good launch can see a lower trap speed.
You do not have longer distance, as that is not a variable unless you run strange 1/4 miles....which wouldnt really be a 1/4 mile anymore.

You're just an idiot using ridiculous examples instead of providing any real world examples other than a max effort dragster. I'm done.

A faster 60 in my cam only car resulted in slower trap speed, every time
If my turbo car has a lazy 60 it doesn't matter much on trap speed either, but if it 60s poorly from spinning trap speed is much slower
Different variables on different cars
A turbo car that leaves soft still has x amount of distance to make x amount of mph, when its spinning its wasting that distance not building speed.
Regardless of his 60 foot, the trap speed is low compared to similar cars.
The guy that tuned his car is very knowledgeable, I'm sure if there was something wrong with the car he would know about it
A combination of a poor 60, high backpressure, 6speed, and first outing in a turbo car probably all lead to less than stellar results.

A data log of his run would help tremendously. It would show how much time (and mph) he's losing between shifts, as well as how much boost he's losing.
Take two 6 speed cars, both making the same power, but one with a blower and the other a turbo, and the blower will usually mph and et better since they do not need to rebuild boost after letting out the clutch after a shift, USUALLY (not an absolute), so no need to start screaming.
The point is, if he looked at his run, he could see how much time and mph he's losing between shifts. Do a driver mod, and see if the mph goes up.

You achieve a higher average acceleration throughout the length of the 1/4 mile, plain and simple. I'm not going to argue with you as I've seen it happen on too many cars. I've seen it on a stock car as well. Better 60' gave a higher mph because the overall acceleration was higher throughout the run. End of story.

The OP hasnt posted for around 3 weeks anyway.
So maybe he has made some progress, maybe he hasnt. But there is a lot needs looked into.

I do know for a fact that if my '60 is worse (spins off the line) my mph is higher. This is if I don't back off the throttle and keep going. This way the car gets a running start that it did not have if it hooked. If I back off the throttle and get back on it, mph is lower b/c then I had less than a quarter mile to run.
