I have read up and searched the question but I just don't understand.

Everything I've read says that if your towing any you should put a TVS 1900 or 2300 on.

But I really want a procharger, mainly because of the prices and alittle bit of the sound LOL.

What I don't understand is why they say get a TVS for instant torque. But its not straight off idle torque that I need when I pull my 24' 7500 pound wakeboat in the summer.

I cruse down the HWY at 1800-2400 rpms in TH mode, so wouldn't that be right in the sweet spot for a Procharger to go into boost when it's needed. The 6.2 has no problem getting up to speed or evening pulling the boat at all right now. I just want something to shut up some diesel owners.

 

The TVS will give you a larger range of available torque at your towing RPM, whereas the procharger will have less boost available and thus less torque. It will be more likely to downshift with the procharger.

 

Depending on how you have the PC pullied, it might only make 1 or 2 psi at that rpm, whereas a TVS will make all of its boost at whatever RPM you are at. The boost from a PC increases with rpm, and you usually set your pulley size based on what boost you want at your highest (Shift) rpm.

Imagine driving along with the cruise control and you start going up a hill. The computer senses you are slowing down so it opens the throttle more, and lets say its locked in gear so it wont downshift. Also both are pullied for 10psi max.

-With the TVS the bypass closes and you get more and more boost up to its max boost of 10psi without the RPM changing.
-With the PC you will only get a fraction of the boost it makes at that RPM. In order to make more boost you must downshift, you might get 10psi at 6000rpm but only maybe 1-2psi at your cruise RPM.

 

Well that's exactly what I needed to hear. The only thing I don't like about how much truck pulls right now is with cruise control on it wants to down shift to much. I just want it to go into the boost and not down shift as much.

 

I tow with a small pulley procharger, typically 7500-10,000lbs i do have 488s
I dont once whatever struggle towing, i dont live in a flat area either

 

You will still get a meaningful increase in tq with a procharger... even 2-3PSI at low RPM will wake it up a decent amount. I doubt you would struggle to pull much. The maggie just has that much more available. In some cases the difference will easily exceed 100 ft/lbs of torque at low RPM.

Atomic's explanation is spot on.

 

also if you want something to shut up diesel owners then look into a turbo, not many street diesels around here are close to my procharged setup

i typically never have to go past 1/3 pedal when towing, and most pedal ive ever needed was 1/2 and even then i have to be smart so it doesnt break ****

with having a 6l80 in that truck of yours you have the first gear in your favor as well as the other gearing, older 4 speed trucks are different and need more of the low end

In the past i pulled 9000lbs plenty of times stock, that is 342s and 5.3 with a tune...Didnt win any towing races but it towed like this for a few race seasons

 

Im not to worried about the diesel guys any way. I've been there done that and about went broke doing it. My lmm had it all but injectors and larger turbo and my Denali isn't really that much slower. With just headers and a custom tune. They are way to heavy and everybody with a bully dog tuner thinks they run low 12 and they don't. I can supercharge this truck and have close to what just a transsimion cost in a duramax.

 

I just don't want to hurt my pulling ability. By picking the wrong kind of boost.

 

In a heavy DD truck I chose a maggie for its insanely snappy power, and ease of use. You can't beat it from that stand point.
