Towing with high hp truck?

I will be getting Casserly Stage 1 injectors, SRP 1 HPOP, and a gtp38r with custom tunes from either DP or PHP and will be expecting 400+ hp. I tow a 22'x8.5' enclosed car hauler with my 71 Mach 1 with tools and parts and what not weighs in around 8-9k. I do plan on getting a 5th wheel travel trailer at some point too. My question is will it still be safe to tow with high hp, will it negatively affect the longevity even more so than just daily driving with high hp? Aside from high EGT's are there any other things to worry about? Thanks for any advice/input.

Just watch temps like you said, don't overboost it, and get a tune specifically for your style of towing.

That's kind of what I figured, just wanted to make sure I spent all of this money on the truck and then can't use it for what I bought it for...towing haha. Thanks for the reply, I appreciate it.

Yeah I am thinking of adding a water/meth kit and just using the water when I tow to help keep the EGT's manageable.

Dont mean to hyjack your thread but in your sig I see you have airbags with your 4" lift. Did you have to modify it for the lift? I am wanting to put rear airbags on mime that has a 6" lift. Thanks!

I know for a fact that my truck has to work less to pull my TT than it did in stock formation. Internet myth gets started when some idiot adds 100hp to a powertrain that was not designed to handle it and when he has a failure he blames the chip or.................? That is why you need to do the supporting mods ahead of time. If the truck works less this has to lead to longer component life. Take the trans, the 4R100 was used and programed for very, very long and drawn out shifts. Install a tuned VB and the shifts are fast and solid. The clutch packs not making contact as long does two things, cut's down on friction, which reduces heat in itself, as well as it extends the life of such components. The 7.3 was detuned because of the weak 4R100, so there is a lot of power that can be brought out fairly cheap. Just make sure to perform the proper supporting mods. Use a good tow tune and you will not have any issues. In my opinion nobody makes a better tow tune than DP. I love towing with my truck, it is a totally different rig when running the tow tune from Jody.

Hey not a problem. Sadly though I am not sure, the PO did the air bags, lift, and tires so I do not know what they did to achieve this. I can take a picture of the set up for you if that would help?

That would be great, I can get an Idea if I need to make custom brackets or not! Thanks
