AGREE -- sounds like you're new to the air-cooled 911 world -- Keep in mind that these cars aren't going to have the straight-line performance of modern cars without spending BIG $$$. However, you might be very pleasantly surprised by how much improvement can be had by getting the stock engine properly dialed in by a person who's familiar with these cars' needs/peculiarities -- this should be done (imo) before any other tweaks/improvements take place.
Roswell's post is spot on too -- doesn't matter how much $ you throw at chips, injectors, exhaust, etc. if your engine's already old and tired -- premature valve guide wear affects a fair % of our 3.2 engines and any underlying wear issues should be addressed before taking other steps to boost performance.
Another alternative for chip/injectors is Sal Carcella, his philosophy is to start with a fully dialed-in 3.2 and go from there -- Sal has also worked with an number of mechanics and may will have a suggestion in the OP's area -- see
