Post Stage 1 question
So I have a 2018 Street Glide. I have a set of V&H Oversized Raider slip ons as well as a Screamin Eagle heavy breather. The bike has been tuned by Harley using a screamin eagle pro street tuner. Headers are stock. I plan on changing out the headers by the end of the year to a V&H power duals. Harley dealer said I shouldn't need a retune when putting on the headers. Do you guys agree?
FYI also for anyone interested, none of this will void my powertrain. Have that in words and writing (email) from my dealer.

I call bullshit on both counts, when you remove the cat restriction, you will need to re-tune it.
your warranty might be good at that dealer only, but i doubt that if you are on the road and have to get it repaired at another dealer you might have issues.

screamin eagle pro street tuner
I did not think it was capable of tuning past stock parts.
dealers used to sell a canned flash for about $150 until this tuner came along, Now they use it to flash a canned map and you buy the tuner which will only work on that bike. Some adjustibilty to timing, afr, & VE maintaining closed loop.
Then again it may have evolved since being introduced.

With a little dyno time, the SEPST can be used to tune for non stock exhaust & intake. No timing adjustments can be made, but VE tables can be modified within epa parameters.
