Soo, if you're looking to tow, and the vehicle is primarily a work vehicle, or used daily for work purposes that require or would benefit from a turbo brake tune, KEEP THE STOCK TURBO if your stocker is gettin wore out, you could always send it off to a place like Danville performance for a rebuild with a larger billet comp wheel and larger turbine (I think..) that would get you a charger capable of a solid 600whp for the fun times and retain a usable turbine break for towing/work duties.
I upgraded to the 4094 and now had that worked over by Mark into a vgt72. The vvt4094 in standard trim is a dog of a turbo, IMO...it's laggy and has a sorta bland power band and as far as a turbine break, forget about it, it's so weak it's nearly pointless...srsly
The VGT72's turbine break isn't much better, although it is better. However it's a beast of a turbo, no complaints about/with it whatsoever:thumb: however, I wasn't expecting to have a "functional" turbine break, although I do miss the stock turbo's turbine break, it'll damn near stop a truck and 10k trailer on a 4% grade! the turbine break of the 4094 would barely maintain the speed of an empty truck on the same grade if not in a gear that generated enough rpm/drive pressure.
Personally if it were me, and I was looking to get 500-550 whp out of a daily driven work truck that tows the weight you do, I'd do something like this:
Lift pump
HD air bags
Built transmission
Transfer case rub fix
Re-build the stock turbo into a "stock hybrid"
3" downpipe
EGR DELETE/blocker plate
I personally would upgrade the y-bridge to a solid 3" unit
Built trans EFI Live tuning w/DSP5 switch
Mod the stock air box (it's capable of moving enough air for 550hp) or get a sweet sealed intake if you don't mind spending the money...
Traction bars, a set of 60" bars for a crew cab or a set of cal tracs
A good set of gauges or a digital interface to read operating parameters
Port the drivers side fuel rail....
A set up like that would take me some time to put together, and when finished would yield a pretty sweet truck with tons of potential for either work or play...and if it wasn't enough for you then, you'd have a good solid platform ready for more when you are
There's a few other things that could and should be done along the way, like lessening the weakness of the IFS and steering rack, a good set of shocks, maybe some 40% injectors and a modded LBZ CP3, IMO UCA's are a nice upgrade for any configuration too...
Lol, that's what I'd do, pretty much what I did before I went to the 4094...:thumb:
Good luck:angel:
