Gryphon questions

[jac443221]

looking to buy a gryphon, just some quick questions. My truck is pretty much stock just deleted muffler with dual exhaust, I am planning on doing the gotts(or the other names it has) modification to my stock intake and dropping in a k&n air filter. With this said should i just stick with canned tunes or will the custom 87 performance do more for my truck? Sorry if this question has been asked just getting a little anxious wanting to buy something and need a lil quick advice. appreciate it.
