Here is the results after we solved all the Whipple Supercharger issues and swapping the stock fuel injectors to 49 lb/hr.

Injectors used are VOR-8F060-005 and the brand is DELPHI rated at 43 lb/hr at 43 PSI fuel rail pressure which makes them 49 lb/hr with GM's 58 PSI rail pressure.

Once owner has gotten dome PCM drive relearn time we will tweak the tune.
Otherwise when owner can he needs to install our 3D smart water/meth injection which will also us to tune for that and gain another 30 HP.

So for a price of a tune, larger injectors and proper use of a OBD scanner to find the Whipple issues the gains were

Before - 313 ft/lb TQ - 283 HP at flywheel to
After - 396 ft/lb TQ - 461 HP at flywheel

Which is a gain of 83 ft/lb TQ and 178 HP


In the end not bad for a very heavy 4x4 that will now surprise people who try and pull on this truck on the road.
