What's a good programmer?
 

I have a stock 1998 ws6 automatic with a 100 shot of nitrous and I want to do a few things to it such as gears and a rear end. I want a programmer that I can change shift points, adjust mph, and remove a rev limiter. Is there anything I can buy that I can do all of this with? I've been looking and there are a ton of programmers that do alot of different things and I want to know which one worked the best for you and which one you guys would recommend!

Hypertech

Can you send me a link to one?

Just look up the hypertech programmer 32500

The 32500 is the correct part number to do the above functions your looking for. Our tuning is designed to work with a stock vehicle with bolt on performance inhancements, I dont know how it would work with the nitrous.

Do a lot more research on here and you will findd programmers suck. Look to one of the sponsors here to the right and they will set you up with a custom tune and do everything you need done and the end power results blow canned tuners out of the water.

Go check out the tuning and diagnostics section for some hard core pcm tuning information.
