Default 89 Corvette Tuning

I have an 89 corvette thats got a lot of work done to it, unfortunately I don't know specifics as it was someone else's project... From what I know, it's got a built top end and a cam. Some trans and rear end work as well. The car is certainly quicker than stock, ~5.7 second 0-60 on the street, but it doesn't run perfect and certainly seems like it should have more power on the low end. I was calling and asking places that could dyno tune the car, but no one in my state is capable or willing to do so unless I get a holley, which I'm not willing to do, so what are my other options? I've tried to research data logging and getting a tune sent to me, but all the threads are difficult to understand. Some help would be greatly appreciated.

Mid rural Nebraska, I called a place called "The Shop" in Lincoln which is all I could find for tuning these cars, they said they haven't done it for years and don't know anyone in the state who does. My plan for now is to buy this https://shop.moates.net/products/ald...46733502218464 and contacting PCM of NC to get a burnt chip sent out to me. A friend of a friend got a tune sent to them from them
