M8 Slip ons and a Tuner?
DownUnder CVO:
Hi,
I just got some S&S MK45 Slip ons for my 22 CVO RGL, leaving the stock header on, do I need a Tuner?
The dealer I bought the bike from says no tune is required, and the dealer that is doing the first service says I need a tuner with just slip ons with the M8 117.

If the bikes runs good no need to tune.
The bigger question I would ask the dealer that says you need a tune is, What is the expected performance increase and will they tune each cylinder individually or is the tune just a canned map download?
if you do the tune find a turner that uses the TSS Master that the first step unleashing the potential powe.
Got Luck

Thanks cat,
The dealer said the M8 117 will run to lean without a tuner, I know on my last 110 I didn’t need a tuner with just slip ons.

My 2017 cvo limited ran just fine with KW slipons, no tune was needed. I would not be messing around with a $50k bike under warranty with aftermarket tuners.

i remember a post by fullsac that stated he ran a m8 on the dyno with NO tuning, and picked up a couple numbers with just a muffler change :2vrolijk_21: my two cents is you will be good to go https://www.cvoharley.com/smf/index.php?topic=123929.msg1533543#msg1533543 check this link
