Need Help W/ Power Programmer
Custom programming is cheaper and better so long as you use a good guy. Hell for the price of the hypercrap you can get real tuning stuff and have actual control over things.

The "performance" tune is useless. I ran it at IRP, both with and without, and there was no difference in performance.
Since you have a 97, the only real tuners available are Lt1Edit and Tunercat. I bought LT1Edit because my tuner told me to. If I had it over again, I would buy Tunercat. Both are $500, and also require a separate scanner package and a laptop computer.
Best of luck.
p.s. If you do use the HPP, it locks to your VIN. You have to take it back to stock before you sell it.
It does lean the car out a little bit, which mine needed after the LT install. And when I take the tune out it runs a little rich and loses a little bottom end power. I think it helps with my situation since I have a decent sized cam and whatnot.

And yea you can run the 160* stat without the powertune. Just select the temp in the programmer and program it in.
