Its really simple, just keep the boost up by accelerating against the friction created by the brakes. Its just braking lol, what's the proper way to brake lol.
Let's say on a 40 roll, go up to 45 or so, give it gas and keep the brakes on till you have full boost and going 40 mph, release the brakes and bam, insta-torque/power.

Drive by wire. Ure car must be rare....... I don't have that..sorry for the sarcasm...... But our cars have a electronic t.b so its moved by a tps sensor on the gas pedal and controlled by the ecm. ....You will have a lag with this as well million second or so but yeah..turbo lag is minimal compared to a larger turbo lag... My lag when. I don't blow my hahn post endtanks is 3500-4000 for full spool............ So don't cry please lol. If you feel u have to much turbo lag look for a boost leak..
Drive by wire is a manual cable that is mounted from the gas pedal to the tb. And is a sprung t.b so it can backlash to its original spot for idle and ect. ...

that is drive by wire smartass. why dont u google it before u make a comment that will get u flamed all day lol.
I was out running with some of my friends and roommates after our football game and i when i stomp on the gas when were running i noticed a small delay, my friend things its turbo lag, i think its that damn drive by wire delay...
Anybody know how bad out turbo lag is? is it truly turbo lag?

I have noticed significant lag stomping on the throttle in 2nd while entering a turn at lower rpms. If you're in the sweet spot in rpms, there is very little lag.

its gay emissions tuning... it takes a full 1.5 seconds for the throttle to open all the way up on an LNF from when you nail it... but it can slam it back to 50% in only a few frames and slowly ramp it back up to 100%...
basically its tq management and emissions tuning making the car harder to drive... it would have made too much sense to just design a new transmission for the cars...

Let me just post up a log of it... seriously my turbo gets to full boost before my throttle body is open 100%
I'll use a thumbnail for easier browsing just click on it to expand...
You can see that I reach my max boost of 207.2 KPA when my throttle body is at like 96%... hence our stock turbos are the bees god damn knees muahahaha

Yea I know but the signal to open doesn't mean a thing if the TB itself isn't open. So like I said, the turbo does spool faster than the TB opens, literally. It is barely anything at all like a fraction of a second... but still it shows that these turbos really don't lag much at all, and the ECU opens the TB super slow in comparison. Since the topic was DBW delay or turbo lag I put up proof that it is, in fact, throttle delay... also note: I am running a 24PSI tune right now. SOOOO the turbo hit 15PSI way way before the TB opens, just an observation and another avenue to discuss.

Not necessarily full boost but it makes a difference on how the car launches. On stock boost 12-13 psi does the trick on 20 mph.
When tuned brake boosting at 20-21 psi at 35-40 mph, the car straight up rockets forward instantaneously. I hurt a lot of feelings when I had my Balt. Lol

Smartass Hmmmmmmm yeah ok....... Since i worked with systems like the so called drive by wire. My terms to Ures who hell cares.. . I call it drive by wire/ drive by cable because of Wut it is..... My friends and old coworkers know what Im talking about. Since they called it the same.. A ssystem like ours uses a potentiometer which causes the t.b .butterfly to open up depending on the potentiometer needle. I understand Wut you are saying. .. I just learned differently... [/B]

Lol........ I will call it to the preference it truly is.... I understand. What you are saying but Im not the rest of the world.........and neither is my training, college and ect.....
It fine for you to call things whatever you like just don't expect everyone else to know what the hell you are talking about. The fact is what you call it is wrong.

I understand our systems called drive by wire. Im not stupid. But i understandmy self call et etc system not drive by wire/ cable since the terms are since similar. Lmao. Lol i swear people on this site make me laugh so much....they get so butt hurt........ Nothing against anyone........... Just funny

Seems like that would stress the **** out of your clutch.
I'm tuned when I brake boost I do about 10psi rolling @ 35-40 mph seems to work better than higher boost for me.

y'all are silly 
.... but really tho.. I know exactly about this lag y'all are talkin about.. I've gotten dusted by a buncha hondas an other POS cars while I'm jus sittin there wit my foot on the floor.. Its not all the time, an it seems random sometimes when it happens... it IS really annoying 2 btw, I'm gunnin it at 30 in 2nd gear an my car jus "uuuuuuggggggggghhhhhhhhhhhmmmmmmmmmmuuuugghhh h, ok now I'll go" for y'all that say theres no lag, jus take a ride in my car
