I have no figures but I don't think there is much of a power increase with the type of hardware we seem to go for in the stage 1.

I think some setups end up losing power from the engine just to have an increase in noise.

 

Stage one has 3 parts;
1. High Flow Intake
2. High Flow Exhaust
3. Turner

This opens the doors for the next 3 stages, you basically set the ground work and build from there into the next stages.
Stage 2 is cam, springs, risers
Stage 3 is lower engine
Stage 4 is top engine and throttle body

I was thinking about tucking my FP3 into that cavity but I've heard they can overheat, so I'm trying other locations

 

Update - found the time and space to rip her on the asphalt after a long time. Early morning 0500, empty roads and cool Temps.
the bike is changed- no stumbling and hesitation at lower rpms even in higher gears. The torque comes strong and I had to check the rpm gear combo to realis that there was none of the lugging I felt in higher gears. The fp3 is off the bike for now (monsoons here) and will be back when ever I get on the open roads. My DK outlaw should also arrive by the time of my next update and then we can be done with the stage 1.

I would like to recommend the fp3 as the first upgrade for new owners.

 

NO, power vision hand down.

 

double post.

 

Be a good fellow and meet me halfway - a tuner of some sort is the to be the first harley upgrade ! My local shop had the fp3 available so I went for that and am happy.

 

did a bit of fiddling with the bike as I found the generics too loud for long rides - couldn’t hear my music full vol and was left with an irritating headache.

the point to ponder is that changing the exhausts back to stock with a corresponding FP3 map led to a resurgence of the low speed hesitation , specially in third and above.

makes me wonder whether the exhaust is the initial limiting element in the equation?? Anyway ordered some fibreglass and tti off DK custom to fit in the generic slip ons. Will update as my stuff arrives and gets fitted.

 

Downloading the stock map and removing the FP3 won't make a difference. Once you mess with the ECM it will always show "RACE TUNED" when the dealership hooks it up to the Digital Technician program. Most of the time, Harley will only void the powertrain warranty on your bike. Good service departments won't run to Harley and tell them that your bike has been tuned. The only time this would be an issue is if your local service manager is an A-HOLE, or if there is an actual powertrain issue that the tech will have to call the MoCo on for assistance and they request the print out on Digital Technician.

 

I believe they can only tell on 2017 and up. And not even sure of that. The people at Power Vision say they cant.

 

What’s the advantage of Powervision vs. FP3 ?
