Externally gated would work out better for you in th elong run I beleive. Turboxs could tune it alot easier as well. But at the same time if its just your temporary turbo no need to spend money when not needed.
Guys- my buddy George has his own site and has just added his own forums.
www.mercop.com the site itself might bother some people but hes my best friend on the force. Anyway, he gave me my own section on the forums. All mine. I can basically do as I please so join up if you want and post away. Mostly cops on the forums along with some gun nuts. Give us another outlet in case the Vivid forums start acting up.
