How can I learn how to use my HP Tuners software? I have the software and the interface cable and the credits. I have been paying others in the past to tune it. Now I have a new engine( ls1 410 Stroker). New turbo (Procomp triple Ball bearing). And I want to do the veriable speed tune useing the 2 bar sensor. This takes time and I want to be able to tweek it myself. Where do I learn all this? Are there books? Are there others willing to teach? Please help. My car has become a never ending series of upgrades and I will never be compleatly done with it, I will always find some new way to make it better. If this is the case I need to be able to tune it myself. I have the tools. i.e. HP ,Tuners software and credits. I now need the knowlege. Please point me in the right direction.
