I have A FMIC with one large hard pipe to the throttle body w/ a TiAL BOV on it and there is one sensor in a bung about 9" ahead of the TB.

• First, what is the best recommended reading to get up to speed, or at least headed in the right direction?
• Is it possible for an AEM EMS newbie to do a decent tune without detrimental results? (keeping in mind that a balls to the wall tune is NOT the objective)
• What is a good laptop to recommend for a dedicated tuner PC? ie speed, memory, etc
• Would it be better to take it to a place like IPS for a full tune rather than try myself and then just learn and maintain what IPS installs?
• Thanks to the learned for the guidance and help

**NOTE: The car currently has a tune that as far as I know is a base level tune. It has not been run at over 7 psi of boost since the engine rebuild, I was peretty much told to leave the boost controller turned down where it is untill tuned differently. (Boost controller is GReddy Profec B-Spec II)

its ok when you know what does what. does the car drive ok? you can do the base fuel map yourself and then take it to a tuner shop to dyno-tune it. but yes new motor you dont want to go over stock boost right now.
