Hello,
I recently purchased a LE5 2.4l out of a Pontiac g6 that I will be swapping into my sand rail. I have two options I can go with here. One, I am able to send my PCM out to a company that will go through a put a tune into my PCM using the hp tuners software orrrr I can just buy the hp tuners software on line from the website hptuners.com and do it all my self multiple times if I have to. My problem lies where they make it sound like they have there own ready made hp tuners tune that they put in it them selves. I am wondering if I get the software my self will there be ready made tunes available and easy to use. I am a gm tech so I have a lot of experience with programming cars.
