Do I need new tunes?

[oasis04]

currently I am tuned for the oem down pipe, gutted cat and muffler delete straight oem exhaust.
I have now added a 3" down pipe 5" straight pipe to 7" stack.
Am I in need of new calibrations?
By the way truck definately runs better with the opened up exhaust.

Truthfully, the tunes don't need to be changed. However, it's not too important to worry about EGTs anymore! You will have a hard time hitting 1200 with a 3" downpipe on any tune with AA injectors.
