Default 98 camaro tuning?

the car is a 98 camaro ls1 with a few bolt ons and a cam. I have a full nitrous setup for the car but havnt tried it out. I want to get the car tuned or get the tune looked at before I spray her so I know its safe. I was told I need to switch to a 99+02 computer to be able to tune it. Is there any way around that or is that just something I have to do.

You do not need to switch to the newer operating system to tune it. I had a 402 with n20 and tuned it just fine on the older operating system. I did upgrade for the sole purpose of having a bigger maf table.

You can definitely tune the 98 computer. I'll be swapping to the 02 pcm so I can have the 3 bar setup and a few other tables.

In my mind there are really no reasons you cant use a 98 computer on basically any setup... I was running a 98 pcm on a 370 Turbo car with no issues...

If by handheld you mean hptuners and efi live, then I'd go that route and a wideband.

98 PCM is fine. Whoever told you that doesn't know what he's talking about.

Of course 99-02 PCM is better than 98, and newer ones are better than 99-02, but it doesn't mean you need to swap to a newer PCM each time GM designs a new one. You can do it if you want to get more proccessing power, but even LT1 PCMs are fine for boosted cars

Any good tuner can tune a 98 PCM there's no need to swap to a newer style PCM.
