I upgraded charge/boost pipes prior to tuning because this is a known weak point.
I will now tell you with experience, this should be be done before adding more than factory boost tables. If you haven't yet, do it! your on borrowed time.
My buddy has a 15 X4 35i 19k on it. We loaded bootmod3 stage 1 on 91 octane. 3 days later the top of the charge pipe- throttle body side blew a chunk out of the end.
Don't be cheap, spend the additional $$ up front and upgrade the charge pipes. not a matter if, but when...
