dont get me wrong, i want to do this mod so so bad, i just dont know if it is worth it. i have read the articles and herd nothing but good things from troyer, and i trust them, mike seems to be a good guy. I just have high expextations i guess. im thinking of purchasing the AF1 intake as well as the excal 2. im just wondering how much of a gain this will give me in performance. i have an 05 KR screw, so it weighs a ton. If i did this will i be able to beat a stock hemi from the stop light? my deff of fast is a dodge hemi or a nissan titan, those are fast trucks, if i did this mod, will my truck be that fast as well? i mean, i want to be able to leave some serious rubber here guys i understand these 2 mods are a huge improvement over the stock performance, but like i said, will it be as fast as a stock 4 door hemi or a stock nissan titan? thanks guys i owe ya

 

From what ive read it seems that it will keep up. Laaunching may not be as good but it pulls hard through the gears. Hope you have Limited Slip.

 

I don't have an intake but, I have X cal ( 1, I guess) and have to say it's a definate improvement.
I don't know how much better xcal 2 and an intake would do. I also have a screw and wouldn't call it fast( I run the 87octane tow tune as performance tunes shift too hard IMO)
I would get it, just don't expect too much.
