has anyone used the hypertech programmer for the LT4?
I have one but havn't installed the program, the first time I
used it, it really screwed up my pcm to the point that I had
to send my pcm and programmer back to hypertech. They did
re-flash the pcm and sent me a new programmer - and it is
still sitting in the box - would appreciate any input:cheers:

First, welcome to the site!

I bought one off e-bay...
I programmed my PCM...
I put in a 160 stat, ran the programming again.

There was zero performance gain with my LT4. Nada, zip.

So, if I had one again, I'd sell it on e-bay! :laughing: :thumbsup:
