i have just thought about something didnt really hit me tell just now....

Does it matter if u get a custom tune before or after u get ur truck lifted?

i dont know if that will effect the results

for that matter will Any other mods effect the results of a Custom tune
like CAI or underdraft pully ect

if so then the Custom tune so be the last mod eh

 

 

anytime you add anything after a custume to it will effect it, adding cai , exasut you will need to have it retuned.

 

then custom tune is the last thing u should do eh
