Power vision tuner with autotune

This is Harleys stage 4 kit minus the 58mm throttle body. I stuck with the stock 50 mm as I bought this package this way and was told that the 50mm should be fine. I did the install last fall and just took it for a dyno last week. I didn't get a chance to do any autotunes last year. I'm pretty bummed needless to say. I posted the before and after tunes, both are sub par according to what Harley claims this package makes. Any apparent ideas as to why the numbers are so bad or am I right around where I should be with how I have it setup? Thanks for the input!

 

I typically see 105 tq and 85 hp from a stage 1 Rushmore touring bike. Sumping wrong, amigo. IOW check for sumping, check cam timing, get a second opinion on a different dyno.

 

Yes Listen to rigid. Something is way off there. The lines don't look like sumping but it still could be or maybe you need a better tuner (not the Module) but something is way off

 

I'd say cam timing as well. Definitely not the correct numbers. Let us know what happens.

 

Máy be just an honest dyno and operator, curves look good

 

Shape of the curve is decent, but it's way down on power. I dropped a 259 into a stock 2014 SGS, W/SEAC and a fullsac head pipe, and first untuned pull made 97TQ 94HP, in 4th gear. Chances are, he's got a mechanical issue.

 

Why do you assume if numbers are way off it may just an honest dyno and operator?
As a tuner I can see there is something wrong, not because I'm drawing for straws or gut feeling or just to add to a thread.
It's way down as compared to most all similar results that have no mechanical or calibration issues.
If the dyno reports way-off numbers it could be the dyno but most of the time it's a problem with the bike.
A quick pull on another, known bike, will quickly determine if it's the bike or the dyno or take the bike to another dyno for comparison.
I assume you've had bad experiences with tuners because you are so hostile towards them?

No if he was a honest dyno operator he would have given the guy what he paid for and Properly tuned the bike and that would include diagnosing the underlying issue before just tuning it and throwing it out the door

 

be interesting to see the outcome, doubt its sumping

get it on happy dyno

 

So you're more for the guy to get bogus numbers from a questionable dyno to make him happy than take advice to look in to why the numbers were so low?
Maybe that's what you would do but as Nick mentioned, it's just a matter of diagnosing the issue that is causing the "abnormally" low numbers.
As an example 1 tooth off on 1 of the cams can cause this.
Fortunately we have tools like dynos, compression testers, and logging software) to identify and diagnose these sorts of issues.
Without these tools in capable hands the owner may just ride his or her bike never realizing the money spent for mods was never realized due to undiagnosed running issues.
Maybe you're right, it's the dyno that Is way off. I guess you would pronounce it an "unhappy" dyno?
So your advice is to just ride the bike as if everything is fine?...at least until he gets beat by a stocker!
