Been into turning wrenches for years on my old square body trucks, but trying to get into tuning so I can continue to do repairs and adjustments on our 2000 suburban, tried to find a cheap way to find a tuner kit so I can do whatever vehicle I wanted, isn't it ridiculous how all these scanners out they say they can do tuning but are just scanners with the elm327 chip in it? I had purchased one of those kess2 clone kits and its interesting but didn't have the exact suburban I needed, so now I'm on the vcx nano and was lead there by pcm hammer, so finally for the first time was able to download the data off of the ecu, and the tech2win thing is interesting, now I'm trying to make sense of the os xdf 9381344 on tunerpro rt.
