I'm sure you could run them but the computer would think you have 26 lb injectors and you would not be getting proper fueling. I obtained a set of 28's and plan on putting them in my car, I have HP Tuners also and compared the two injector tables in the computer for the 99-2000 26lb'ers and the 01-02 28 lb'ers and they are different. If I were you I wouldnt put them in unless you get the correct table tuned in.

98 and 01-02 cars had 28lbs injectors, 99-00 cars got the 26s. GM did use two different PN's for the 28lbrs. FWIW the 98 injectors where PN 12554271 and the 01-02's should be 12561462. From what i understand both PN's flow exactly the same.
to the OP I would plan on getting your car tuned if you are switching to the 28lb injectors.
