2007 ultra classic currently with a pc111 on it from2 miles on it. trying to get some feed back on sert and thundermax with auto tuner systems, my pc111 has taken a crap and i'm wanting a different tuner because&nbsp\\; this one didnt last long and have heard that they dont work well on the 07's ? any info would be appreciated. I have rush pipes and s/e air filter setup. bike currently has 19500 miles on it with no engine modifications

 

Hard to go wrong with the Thundermax. I've got one on my 07 ultra and it just gets better and bette as it autotunes. "Set it and Forget it" You pay about double what the pc3 costs, but you don't have to dyno it ever. Keep upgrading, new map, autotune, no dyno. Great product. I can't say enough good about the Thundermax and Zippers. Excellent customer support from Bill, Randy and the whole gang.

 

thuinder max seems to be great if you have lil computer knowledge.Im one of those whos total gear head and it was pain in the *** for me.If I can see it I can fixit,modify it and make it fast,this black magic **** is&nbsp\\;problem for me.I had to get some computer nerd to talk to tech and get it working.Image a guy who has no idea what lobe seperation or duration is tuning a engine?

 

If you got the PC-III from Fuelmoto, there should be a two-year warranty on it.
