Best LBZ turbo for hauling?

I have a 2006 LBZ, fully deleted, EFI Live with custom tunes, 3”downpipe, up pipes, fuel system, etc...Just looking for some advice on a new turbo. I haul a 30ft Horse trailer a good bit. I don’t want excessive EGT’s... Looking at the Garrett 4094 or possibly the 3794. Any recommendations? And will I have to get new tunes written for a different turbo? I’m a little ignorant in this area, lol.

stick with a 65mm or smaller turbo since you tow and don't want excessive EGTs. New tunes are not required, but will definitely make a difference in driveability and EGT control.

I’ve heard bad things about the Stealth 64, but a lot of people recommend for towing heavy. Not sure whether to go that route or not

I'd recommend leaning towards a brand new 3794. Garrett makes the Powermax Stage 1 which is a 65mm. Great turbo for the price.

I’ve done all of the other parts myself, downpipe, up pipes, etc... is it going to be possible for me to do it by myself, or is letting a shop do it recommended?

My stock turbo started making a vibrating noise when it spools down, is this normal?
