heh, not all the time!! But again you get what you pay for Nelson tunes are badass imho and to top it off he puts up with all my b/s changes and sends me new tunes all the time! I want to change shiftpoints and cam, no problem. new PCM is here before the parts by a long shot. I dont even remember what I paid him for the first tune at this point. And btw I still have my diablo to monitor the engine sensors till I get a wideband O2. After that the predator will be a paper weight, I am not even sure I would sell that piece of **** to anyone.
