All are needed to start an improvement plan.

Lighten the car as much as possible . Have the car 4 corner scaled to see where weight needs to be moved / adjusted . Any adjustable suspension components ...... shocks , upper / lower control arms ?? Like Chuck said , video of the launch up close . Need to see how the suspension is working .
What is your 60' now ?

 

[dynoman]

More boost or ramp in more boost you're only at 26psi . Is the Haltech controlling the boost ??

Those more knowledgeable step in. He's got 3.73 rear gears and is running a 26 inch rear tire. Is that the best combo for a short time?

At 10.27 you should already be mid 6s
Unless you you are making it up after the 330ft

For a fast 60ft and 330 The problem is 26 doesnt leave alot of sidewall to take the hit so the suspension needs to take the hit.
The gear helps the car off the line if the traction is there.

26" and .373s puts you in the .410 range if you weren't aware, not the greatest ratio for a low revving motor

Bigger tires and leave harder.

 

[Chuck Leeper]

Still no data.. Not sure what " faster 1/8 times and 60 foot" means without it.
Also I see that the 26" tire is a class spec... Not good with that limitation? Don't know, no data to compare.

Faster or quicker

True but either way, going that fast the car needs to be on 28 inch tires. That alone will pick it up.

Back in my day, 28s were the biggest thing you could stuff in there with the wheels available and then you needed airbags or springs to keep the molding lip from eating up your tires.

Lost a few tires on 28s back in the day.
