Some comments there as well.
It seems to me Wetterauer has a nice design allowing for easily returning the chip to the stock setup, but their chip is four times the cost of the Upsolute chip. Sometimes maybe you do get what you pay for?
Your point about the crimping is well taken, that is definitely to be weighed.
I hope to get more comments, opinion, and most assuredly some chiding, on the subject, including more info re pulleys, and any other reasonably cost-effective mods.
Thanks again to all,
