Tgbstang

Anyone here use the Anderson Motorsports PMS? How user friendly are they? Im looking into buying one but more than likely i will be the only one doing the tuning. I looked at the instructions that they offer on the webpage and i understand a little bit of it but it may help if i acutally have the PMS to follow along with. Any input? I have been looking at stangtuning.com and there is alot of help there, but i just want to know if this is worth the buy and if the normal mustang enthusiast can pick up on this and use it to there advantage.
