91RS/SR355

I am building a 355 to put in my 1991 Camaro. Its a completely rebuilt 4 bolt main 350 intended originally for racing in my 64 Nova but I am swapping the high rise and four barrel for a Holley Stealth Ram. I have a computer, full wiring harness and a dyno tuned chip from the guy i bought it off of. The only problem is of course it was dyno tuned to his setup. Does anyone know where I can retune this to my setup or a place that dyno tunes near Columbus, Ohio?

Here are some pics of the car and motor so far.
