    Question 09 ls3 corvette fabricated manifold and 102mm throttle body tuning

    Hi I have a 2009 Chevy corvette ls3, my car is already tuned for a
    slp cold air intake,
    Texas speed stage 3 cam kit,
    Longtube headers
    ^currently tuned for^

    Sheet metal fabricated intake w/fuel rails
    102mm throttle body
    ^new parts^

    This is my first time attempting to complete my own tune (car was previously tuned by another tuner) I read some forums about throttle body tuning involving scalar and the throttle body ratio formula. I could not find any forums on adjusting the tune for the aftermarket intake manifold. Just looking for some advice in terms of what I exactly need too adjust. If anyone has a link to a good forum on intake manifold tuning that would be great as well.
