What kind of gains would I be looking at in the 1/4 on a 2010 GS with a halltech super bee, ported throttle body, kooks long tubes and a tune?

The tune will be your main benefit. The cold air wil help, and the headers, but at a high h/p to cost ratio.
Oh yeah...the question....I say 2 tenths.

PS: Get a base line 1/4 mile time before the install if its not to late.
"OR" do you already have one?

From what little experience I have a 12.5x base line would really be a kick a$$ awesome time!

I dont have a base line, but I do have a track near the house. I Know you get about 40 rwhp from these mods, just wondering if they are worth doing or not

Probably 8-9 tenths, depending on the quality of the air where you are.

In southern Louisiana my 2008 vert went:

Stock w/runflats - 12.75
Week later changed to Nitto Invos - 12.50
Dynatech headers, vararam, no tune - 12.10

Haven't had a chance to run it since the tune and ported TB and manifold, but I'll guess I'll pick up another 2 tenths.

Definitely not .8-.9, but .4-.5 would be a reasonable expectation.

My 2011 GS 6 spd manual went 12.80's stock (It was hot and so was I). I added a Vararam and went 12.61 (will go 12.5's for sure but I think all it did was allow cool air to the air temp sensor). I added a 160 stat, then had the tune tweaked to get rid of the torque management, lower fan turn on speed, he added a touch of timing up top, I am guessing 12.20's @ 117 - 118 in this configuration (It's been raining non stop since). Next up is a cam install and under drive pulley, hope to see 480 rwhp and 125 mph trap speeds, ET will be a guess on the run flats.
