im really convinced about the adrenaline i migh sell my comp to get the adrenaline.....
i was to get a smarty to stack but i dont know still....maybe a adrenaline/smarty/comp stacks

 

from what i have heard, the adrenaline gets as much as you can out of the computer. quad says that it was built to be a one box upgrade. they say that even if you stack it that it won't produce anymore power. thats just what i heard. i am very pleased with the adrenaline and am going to load one of the updated aggressive tuning files on it today. the only problem is that i dont drive my truck very often anymore to enjoy it since fuel prices have went up so much. the only problem that i noticed is that the adrenaline is bringing my 47re to its knees rather quickly. when i have it in the highest level it will get extremely hot and will start to slip rather bad. once the trans is built then i should see a major difference in the truck.

 

that the kind of thing i have heard who make want to switch
