Twins

With as much weight as you are pulling, just bite the bullet and put on twins with an exhaust brake. You wont be sorry you did . Then you can put a lot more fuel more playing and still keep egts under control.

I would say 50hp nozzles with a stocker/S400 setup.. You can get over 600hp on 50hp nozzles, so that should be plenty, and when empty the 50's will offer an improvement in economy.

If I ever decide to build a 400-450 hp tow truck it will be configed like this..

Stock airbox w/ PSM cool air duct and Airraid torque tube
GDP Intake Horn
PDR or Hamilton Stage 1 Cam
DDP 50hp Nozzles
Stocker/S400 WG set to 40
Exhaust Brake
Smarty Jr

That should make for a very reliable and cool 400-450hp, and will spool very fast thanks to the Cam and stocker on top.

If you want more power than that it would be easily done with programing and a little more boost.

if you throw some 100s in there with those twins and a smarty you'll be really happy. i'd say you'd be over 650 hp.
