my buddy is looking for tune for his auto transmision. He was looking at the H&S tune but i suggested the co-pilot. What are the opinoins on them and which is better? he is leaning towards H&S since he has the xrt

H&S OD is a bargain compared to co pilot and B&G TCM tuning. I've only tried H&S and B&G and I prefer the H&S software. Its not perfect but 100% better than stock. If you can't lock the TQ Converter on command then why even bother with a $1000 plus co pilot

yeah that does make sense. was it worth the money for the H&S?

I put the H&S XRT trans programming on my 2011 duallie & love it. I own a Transmission shop & know how difficult it is to get a 68RFE to shift the way H&S has done, Best money spent on truck so far.

The H&S OD tune was felt like as much of a gain as goin from no tuner at all.
