I've been using an ACCEL SLM for the past year or so and thought I would post my experiences with it. It is the SLM05 that fits 08-09 Touring.
Have changed out my exhaust twice, changed breathers twice and added SE255 cams during this period and the SLM has performed perfectly after each change out. Just finished a Ported 103 Top End and it DID NOT adjust to the change. Contacted the company and Tech guy said it wouldn't handle the build so I changed over to a SERT.
I have nothing to do with the company--was just looking for a tuner that I never had to mess with and this thing filled the bill for me.
