Absolutely you're going to need a custom chip to make a camshaft that large work with a TPI computer. Any one of those three are good intakes.
Ask around amongst your fellow car guys, there has to be someone in New York who does custom chips.

 

prom or a whole computer ? like hypertech sells one and jet perfromacne sells one or should i find someone who burns em?

 

dont waste your time with a hypertech or jet chip or anything equivenent to that.

you will need to have someone custom tune the car if you ever want results

 

The PROM. And as LoneStar and I said, you need to find someone local to you who does custom chips. The Hypertech and JET are for stock engines, and they dont even do that very well.
