I have a 1995 Gutted GSX engine is a forged 6 bolt 1g head bc 280's and bc valvetrain holset hx super 40 with 19cm exhaust housing been messing with launch control settings and what would be the best setup settings for both anti lag and two step to get me some good 60ft times? I currently have my 2 step set at 5500 rpm and rev limit set to 8k now antilag is 5450 rpm -3* and no fuel added is this wrong? open to any and all suggestions.
 
You shouldn't need anti-lag at all. Unless you're using a HUGE turbo like a 42R, anti-lag just breaks stuff. With a FWD, anti-lag is giving you no advantage on a launch whatsoever...in fact, it probably hurts more than it helps.

Dave's not even using Anti-lag at all, just launch control set at around 6K.
 
just using a "2 step" should be enough. Like Jusmx said, Anti-lag is just going to break shit. I've only used it once and that was because I was being a ricer and wanted to shoot flames and black shit out of my exhaust.

Just practice launch at different RPM's and when you find what works for you set it there.
 
Lmao, full boost off the line isn't ricer, and neither is being able to set your limiter much lower because of it, therefore you won't always wash out your tires particularly if you drag with street tires.

In addition, you only break shit if you are that dumbass who antilags at every stoplight and holds it for a long period of time. The only things you can break are your turbine, turbine wheel and your exhaust manifold. None of these will break if you are smart about what you are doing.

OP, if you try antilag, experiment with lower rpms too, or you may just want to try stepping on the 2-step alone for a-while, and see if you can gradually build boost that way. I've read that some people still have success with that too.

Just experiment and use what works best for you
 
I never said full boost was ricer, I simply meant that anti lag is more than likely not needed for his application. Anti-lag with a 16g is definitely not needed.

Who the hell said it was?
 
I think the concern with breakage is more axles, t-case, differential, ect.
Leaving the line at full boost obviously causes excessive drivetrain shock. More boost=more torque=more chances for breakage.

The key is obviously finding that fine line between bog, spin, and breakage. Most people can get away with only 2-step and most I know actually try to leave with very little boost. Slipping the clutch (if 5-speed) will immediately load the engine and cause boost to skyrocket anyway, so you really don't need much to get you out the hole. Every ones setup is different , and things like tire size, tire tread, flywheel, and track prep to name a few, all play a part.

I personally leave at 6-7 pounds on just a 6750 two-step.
Try just a two-step first and slowly raise it if your bogging, until you find the sweet spot.

Good to know man, thanks for the info!
 
I have a 70A/R hx40 with meth. Using antilag at the line with slicks for over a year now, come out at 22-23psi in 1st gear by redline in 1st I'm at full boost 31-33psi my 2step is set at 5500, not too sure on the antilag settings or if they will help you since I am on meth I have the fuel enrichment set way differently then a car that's only using one type of fuel.

My theory on the whole antilag good/antilag bad debate is that I think the interia a motor is making spinning at 6+ K compared to 5K is a lot more so thats why I choose to launch lower and use antilag than set my 2Step to 6500 and make the same amount of boost. Im sure there is various theories.
