Where does the power come from?
Some truck will run stoich at wot, those you add fuel to make power, other vehicles are rich from the factory and you need to remove fuel.
most ls1 cars do not get 25 hp from just a tune.

My stock LS2 was in the 20-21 range, now with the tune it's as high as 27, so clearly some power was made there. Add in better fueling at WOT and you can gain some 15rwhp from just a tune...idk if 25rwhp is realistic on a bone stock engine.
