Worth to upgrade from FP3 to power vision

Hear me out before you flame me, I have the FP3 and did a stage two with Andrew’s 57H. Bike runs fine no complaints but I have a feeling I can get more out of it with this set up. There’s no question the power vision is better. My question is, is the cost to upgrade (400) worth it as in bang for buck. Would I just be spending 400 for maybe a 1% difference or would it be night and day? Thank you in advance.

What are the numbers you are making? Hp tq? Dyno sheets? And what are your future plans as far as engine upgrades.

Tough to quantify a feeling. For me it was worth it as my cam change and fp3 support left me unimpressed with how it ran. Not wanting to Dyno nor having a tool to view logs and the good reputation of the PV and Fuelmoto, the change over was an obvious choice. My bike now runs great, I can be the do it myself person I try to be and have a tool that can be used if I do need someone to assist or decide to go further with changes.

Called fuel moto and the salesman on the phone said if the bike is running fine and not bogging then the power-vision and tune wouldn’t have much, if any difference at all over the FP3.

FP3 tune vs PV tune

I installed a cam on my 2020 FXLRS, it was a unique cam with extremely large sustained duration compared to most M8 cams. Initially the bike had trouble even idling using the closest match that FP3 had available as a baseline, spent 3 days on the phone with FP3 tech line and they finally made major adjustments based on cam specifics, A for effort. Bike ran “ok” but was getting less than 100 miles on a full tank and you could smell raw fuel coming out of tail pipe, power curve was a small window between 2800-3800, fell on its face around 4800rpm. Also seemed the power came on all at once, like a 2stroke.….

Overall I was satisfied with performance and just thought I picked a bad cam grind.

Until I made the switch to a PV and had a specific dyno tune for my bike,

I went ahead and had my tuner do a pass with current FP3 tune, it had 98hp and 99ft lbs tq, it actually produced less power than stock at lower rpm ranges, and then fell off after 4800rpm.

Same cam/pipe with new PV tune produced 129/128!!! Bike now gets 225+ (More than doubled what FP3 got) miles per tank of fuel.

Also, the power curve is broad and very smooth between 2,000-6,000+++ with massive low end grunt.
