Have the transmission and drive line modified to handle the increased torque and horse power. You woud be better off buying a different truck.
Does the truck have variable valve timing? If so, I'm thinking you could adjust cam settings through tuning. Not sure how much variation you would have, though. Also, while you couldn't change static compression ratio, by playing with the valve timing I think you could affect dynamic compression slightly. I have no idea if these would be feasible- just throwing out some thoughts.

No it doesn't.
As I mentioned, I've recently had a Black Bear tune done which much improves the notoriously bad factory tune. The tune also limits, or eliminates the power robbing torque management from the factory.

Black Bear Performance :: Custom Tuning Solutions for 96 and newer GM Vehicles

My research revealed that the cam that is stock on the LQ4 is the same as the 2002 Camaro LS!, the LQ4 has more cubic inches than the LS1, but the block is iron and not aluminum, the LQ4 317 heads out flow the LS1 241 heads and with a simple tune, the 300HP LQ4 can surpass the 345HP rated LQ9 6.0 that came in the Escalade/SS etc, they are severely detuned from the factory.


It will be interesting to feel what the difference is just with the new ECM flash with the Crusader in tow. Can't wait.

Go to PerformanceTrucks.net Forums. It is a sister site of ls1tech.com. It is primarily a racing site like ls1tech, but there are plenty of guys that tow with s/c. The magnacharger is ideal for towing as it produces massive tq just of idle. You will want to add an larger aftermarket transmission cooler. Ask around over there and you will get a ton of advice and real world experience from guys that tow.

Good info, thanks.
I've been there and you do have to sort out the many street racers from guys like us. Lots of rave reviews regarding the durability, design and tuning options for the LS platform.
The comments and experiences there helps build a good case for the TVS1900 on my stock LQ4.

I see you joined pt.net. I am a hot rodder at heart. I haved towed several times with my truck, but not in its current form. I would not hesitate to tow with a ls1 platform and a magnacharger. Especially with the 4l80e behind it.

OP, your 6.0 is a LS based engine. Adding 6 psi of boost is nothing for its stock bottom end. However, I would look at a Procharger as you will become very tired of the "whine" the magnacharger will produce.

You can get the procharger with a tuner to remap the ECU. But you will also probably need a bit higher psi injectors as well. You would really need to speak to the company that supports whatever charger you buy about it.

But you will need to address the drive line, beefier TC and probably just add a trans-co shift kit to the trans.

Procharger will not give the low end tq that a roots s/c will. The newer TVS s/c is extremely quiet compared to the older model roots s/c also.

Money money money cause ya hate Diesels. With a S/C you are going to want to show the Diesel guy's how much this bad boy has. There goes your mileage. Most of us never did squat to our trucks.Get a DIESEL

The mileage savings on a Diesel compared to a Gasser is a joke. My experience with the past 5 Diesel pickups and 2 Gassers is that the savings is not there for it to even be a consideration. Especially when you consider that diesel on average is $0.50 higher a gallon.

My pickup sits at 11 mpg empty and 7-8 mpg towing. The only two diesels that I had that got decent mileage was my 96 12v and my 04.5 3500 Cummins.

This guy will be ahead of the game SC his gasser if that works for him.

We have a winner.

Mileage? Y'all are really worried about mileage with towing? Like the few cents of difference between the 8mpg gas and the 10 mpg diesel are really gonna break your bank? When you've already shelled out a few thousand for your camper? In case you haven't noticed, this isn't a cheap hobby/pastime/pursuit. Supercharging is throwing good money after bad, unless you're just taking it to the drag strip. For towing, diesel is the right tool.
