Hello all. Have recently joined TDR, have been reading the forum for months and have learned a lot. I have been thinking of purchasing a Superchips tuner or an EZ. My trans is stock and when I do tow it is about 9000lbs. I have not upgraded my trans yet... still under warranty for 30000 miles. Would my trans hold up if I added one of these and which would work best? I have already added 275's and gauges. Thanks in advance for any replies.
