Let me know how tough the learning curve is with HP tuners. I use computers every day and have been thinking about buying and getting to know the ins and out of tuning the LS motors. Like anything, I'm sure it's a matter of understanding the user interface, but have never heard how difficult that is
self teaching.

Chris thanks for the information that is what is great about this site a lot of info. I like the sound of flomasters also just not sure how a single muffler (of any kind) will sound so need to do some research.

I paid about 400$ on the C10 truck tune and it still needs some trans tuning so I don't want to spend anymore money to someone else. figure I will spend it on learning material....All the tuners on this site say read ,read, read, and read some more!!!
so now I just need to learn to read!!!
