rtt.by Review:

GREAT BOOK, GREAT EDUCATION! Everyone concerned about general health and wellbeing should have a copy of this book. It's worth 2X what I paid for it. Have been adopting its remedial recommendations for combating my C-R cancer. Wish I'd learned about Natasha Campbell-McBrides research and discoveries 4 years ago.

I had been waiting since day one for a tuner for my 2012 r/t classic, so my expectations were a little high. The unit does preform great. The first time I ran the tuner on my vehicle I discovered I had to leave the ignition in the on position the whole time during calibration and tuning (even when it says to turn the ignition off) that was the only hiccup. After that, the tuning was a breeze. The ability to turn off the MDS alone was worth the price to me. As far as performance increase, it is noticeable but not mind blowing. I was running 0-60 in 5.6 sec before the tuner and 5.1 sec after the tuner to give you an idea. The device itself feels cheap and fragile, but I can get over that. All in all its a good investment for my challenger.
