I got one from Steeda and have not found that, but I haven't looked for it either. I did adjust for a gear change. I just recently revised my diablosport predator tuner via my friends PC. Their tech on the phone help was awesome. I've never used a PC, only MAC platforms. I bought the required serial cable, tip and power adapter from radio shack. Took about 10-15 minutes for me, but would be much faster if your PC friendly. Good Luck !!
