Default Stage 1 - What tuner are you using?

I have a set of RCX slip-ons (cat in place) and I am going to purchase a screaming eagle wedge breather.

Harley recommends a tune for this stage 1 upgrade. Their screaming eagle tuner is $450…

Did you do the tune with your pipes / breather? Did you use the Harley tuner or something aftermarket?

Are you under warranty and want to keep it? If yes, then you need to use the Screamin Eagle Tuner.

I used the Harley tuner on my 24 because I wanted to maintain warranty.

for a Stage 1 SEPST is just fine..these bikes run good and strong stock and a little better all around with SE Stage 1. If I were to use a quality aftermarket tuner I would insist on getting a dyno tune by a well respected and reputable operator to get the most out of it...I even just used the SE Stage 2 calibration on my 25 and it runs like a raped ape...very satisfied
