so i'm thinking of buying a manual boost controller, mainly a hallman or turboxs.

turboxs offers a standard and "high performance" model and so does hallman.

my question is if the higher end models really make a difference? turboxs claims that it will spool the turbo faster but idk. anybody have any first hand experience?

 

Go with the regular. The regular is turn up or turn down. The HP is a turn up and adjust with allen wrench on the side. It will become a hassle for those on-the-fly power boosting needs. You won't notice a difference.
