Its about total area under the functional power curve more so than peak numbers that generate the fastest times. This will determine how fast your car is more so than peak numbers. For our cars most of our speed and track times is determine by how much power you are making from 5k-7k rpms (stock redline). Our driveability comes from idle to 3k rpms though.
With a turbocharged car in a drag strip setting it doesn't really matter because as they say, lag only occurs in first gear. Thats saying is true and for the 3s specific world all our records are held by TT cars.
TT works better on a V design engine while a single setup would suit a flat or inline setup with the way those exhaust are usually setup. For the everyday person you can't gather lag or the perception of it on a dyno or even from track numbers unless there is a issue with respool between shifts (BIG ASS TURBO).
Lag is not only how early or late the bulk of your power comes in but to me its mainly the amount of time it takes for you to give it throttle and there is a appropriate response.
All you need to decide is what do you want out of this car power wise (goal either AWHP, ET, or traps).
After that look up people who have already accmplished your goal

Hit them with a PM or get a number to actually talk to them and go from there. Ask the what to do and what not to do, the regrets, and or problems they have run into with there choices. Compare that to the $$$$$$ you are willing to spend and it all becomes clear.
You have options all the way from a nitrous power 9b car all the way to custom 6g74 with 4088's to choose from as far as how elaborate a setup you want to go with. Time and $$$$$$ makes the rest of the decisions.
Oh the larger setups (3037's, gt42, dr1200's, twin gt35 setups, twin 4088 OMG) don't hit there boost until 5500-6k rpms on our 3.0 litre 6g72, go to a stroker or 6g74 and of course that number will lower. Evo 3's are not really that large by comparison and they will get you 15 psi around 4k-4500 but usually 100-200 more AWHP than a tdo4 counterpart.
You got options though which is good.
