Need a programmer of some sort bc i changed my stock 342 into 373 and my spedometer off..dont want to spend a ton on this but any help would be appreciated.

 

car is a 97 trans am manual

 

The programmers out there are Hyperthech which I have heard Very little good about if you have a standard which you must with those gears. I have LT1 Edit and i like it pretty well but its $550 at carputing.com. Madwolf who is a member of this board can do it for you and I've heard alot of good about him but I don't know what he'll charge. Last time I checked Superchips they only offer a program for LS1 but they may have one out for LT1s by now.
