Chip and Tune Question

[ABBEZR1]

I just purchased and installed a New B and B exhaust system and was wondering if I needed to have a chip upgrade to get the full effect of the upgraded exhaust system.

My Z is a 90 that from what I can tell is mostly stock. It has a front air system in the license plate filler and has a plenum spacer that someone before me has installed. I do believe that it still has the stock injectors, plugs coils ect. I'm thinking of ordering Marc's DVD and doing the plenum removal and checking everything under. I would like to wait for a new chip until I do the under plenum inspection but wasn't sure if I needed to do it sooner because of the exhaust work?

Sorry so wordy for a simple question.

Thanks,

Steve

If u haven't put on headers, I doubt u need any tuning assuming everything else is stock.
