It doesn't take long to get it up and running decent using a preconfigured tune but you'll probably do a little tweaking for your combination.
There is a learning curve but for me it took longer getting familiar with the software than actually fine tuning my setup. There are some videos online you can watch to give you an idea of how it works and what it's capable of. If you run a cam with a lot of overlap then tuning in the idle area is a little more time consuming but if you run a mild or stock type cam you can almost call it plug and play.
If you're seriously considering it then download the software (it's free) and play around with it, There are two help buttons at the top of the software that will direct you to all the help files. One says "Help ?", That one is pretty handy, You right click it and your pointer will have a question mark floating with it, You can then move your pointer to anything on the screen and right click again and it opens the help section for that particular topic. Holley put a lot of thought into making the software/system user friendly for beginners and still have all the features for advanced users.
One thing that is really helpful is that you can save your tune like you would any file you save on your computer, That allows you to make changes on your tune and if it's runs worse or you simply screw up you can go revert back to your old tune in a matter of seconds.

Does it have a plug in for the alternator? I was reading some comments and it said that it did not or you had a connector you could program. Bought a TBSS Intake and I'm really considering buying the Holley Terminator Max System.

I don't think they do, I'm running the Dominator and HP version but the harnesses are the same. You'll wire up the alternator separately, It's not difficult to do. The alternator I used on my S10 has only two wires to hook up but that may vary depending on the alternator you have. I have a local guy that rebuilds alternators so I always ask him If I'm not sure about a particular alternator. Here is a basis diagram

IMO 6.0L Iron engine + 4l80e is for turbocharger only
Any Iron 4.8-6.0L Engine needs a turbo

400~rwhp from 6L is really unfortunate. There are 2.0L Engine factory near 400rwhp, and 3.0L engine which factory more than 400rwhp.

IMO get an aluminum 6.2L+ engine for naturally aspirated application

my opinion is based on availability of 400rwhp 3.0L Engine which offers 6-speed transmission and ~27mpg (or auto and 23mpg)
the 3.0L can be used up to 600rwhp reliably for 20 years and 250,000 miles, so it doesn't make sense to use 6.0L to make less power with a heavier engine, does it

4l80e is a monster capable of supporting 800-1000rwhp also and eats 3-4MPG (over similar 4-speed lighter automatics) because of it's incredible internal rotating parts.

Random 3.0L dyno graph to compare with


They 3.0L make more torque, more power, and the vehicle is heavier that they come in, so to use 6.0L and have less power and worst fuel economy is silly?

Another random 3.0L stock engine/fuel system etc...
6L won't ever come close to that without a turbo, and will never match the economy.
The only way to 'beat it' with 6.0L is 800rwhp+

Why ignore the outside world?

You think it's okay to just sit in the place, never looking outside to see what others are doing?

What sort of magical interventive measures can you steal from other configurations? To make them your own.

Aren't there some really inventive imaginative engines configurations out there we can learn from?

What I see is 3.0L doing more than 6.0L in a heavier car than what is being used here.
So something is off. WTF indeed? How does aristo-lexus vvti 2004 $1200 3.0L engine produce 800ft*lbs of torque by 4400rpm?
We should look at it and learn from it.

Is it the compression?
2jz-gte have 8.5:1 compression

So it's not the compression.
Is it the displacement?

2jz-gte have less displacement.

So its not the displacement.
Ah, I think I see the problem.

It's the turbocharger. There is nothing superior about 3L or Toyota. It's literally the similar torque specs and aluminum parts, the same kind of bolts and spark plugs are used.
Even the head gaskets and cooling systems are similar. Even the crankshaft girdle support was added properly to LS. By 2002 you basically have a 6L toyota motor sitting there.
It just comes without a turbo.

All you have to do is add the turbo and double the output 800.
The rods, pistons, crankshaft, they are pretty much the same as toyota 3L, that is, pistons are a cast piston fragile alloy which can go 250,000 miles reliably if treated right. They need to be cooled, carefully, controlled. The engine will only last if properly controlled (fueled and cooled etc...) so there is a learning curve for first timers

Anyways I am not suggesting you install a 3L engine. I am pointing out that you basically have a two of them, both are turbo-engine and a turbo-transmission, which are costly to maintain because they are so robust and 'ready for action'. But you are using it as a naturally aspirated platform. Which is silly, might as well just go back to 3L (not really but you get the joke, as if 3L would just fit right in... I have a feeling alot of my posts are being taken too seriously and it's jokes that are being ironically missed)

maybe it will help if I point out that I am entertaining, using this venue as entertainment, when the realization dawns on you the anger should become embarrassment over whatever jokes pissed you off so bad you wanted to ban the 'troll' who is really creatively disguising his teaching efforts. Otherwise the post looks like this:


put a turbo on it
and then it gets men likes which is not something I am aiming to collect

Dude I came into the thread, and see you looking for more power. I fear you are about to be nit picking over 30 40 50 horsepower, dimes and nickles, when you have +400hp sitting right in front of you with basically no consequences if done right, the right combo of parts will double the output of that engine tomorrow and it will still drive the same manners.

those two are absolutely no help if they didn't at least mention the prospect turbo. it's like they have turbo block.

is that a thing? I think those guys are turbo blocked, can I say that

In all fairness, the 100% stock original untouched 1999 3.0L 2jz-gte does 440rwhp with factory turbochargers from USA engines (not JDM)

So... comparing a stock 3.0L from 99 to the stock 6.0L from 02-06... close enough to be apples. And one has more power... and comes in a heavier car.
But this aint about that. It's about preventing the 'nickle and dime' scenario most n/a engine owners face at this level.
The barometer and temperature is going to change tomorrow and it will lose 10hp that will be missed dearly

Guys what he is saying in a nutshell is that a turbo 4 banger currently puts out what hp I have so why not double my hp by putting a turbo on mine instead of little power adders. He's just being poetic about it. He ain't promoting 4 banger crap.

thank you for understanding so perfectly and clearly.


to continue narrative briefly, the naturally aspirated crowd has to fight tooth and nail for every 1hp. It hides in crevices, angles, vectors, shapes and style, conditional dependent moods of the atmosphere, moon sun altitude zodiac and rain can alter hp up and down.

With a turbo all of that goes away more or less. Instead, you just have a dial. I call it 'dial an atmosphere'. The same as if you drive up sea level and the air gets thinner, you can drive below sea level (boost) and the air gets denser. Use the dial (electronic boost controller) from the driver seat to control torque setting in synchrony with engine computer for maximum performance and economy.

So where could l get a bolt on system for my lq4 in this old firebird? I'm and aircraft mechanic l'm good at aluminum fabricating but not welding and things. Would prefer a plug and play as much as possible.
