Just remember the old adage, "You get what you pay for."
....and its corollary, The more they pay, the more they think they get.
I have found that the more people pay for things, the more likely they are to find improvement. If someone spent $400 to improve their ride, they would be looking for an improvement, and will find one from their 'butt sensor'. But not a big one. Powder coat them red, put a lifetime warranty on them and charge $1500, people will report that those improve the ride more than the plain black ones.
That has been my experience in the automotive/truck and golf cart aftermarket.
We used to ALWAYS do one trick anytime we did engine or brake work - move the operators seat ~1/2 - 3/4 inch forward. The operator now feels that brake pedal response is MUCH better, car pulls harder, engine is 'snappier'.... after we install a chrome dress up kit and paint the calipers red.
Engine air intake makes it noisier in the cabin! Must be all that HORSEPOWERRRRR!
Sure, scientific devices
mounted to the leaf spring show improvement. And who rides on the leaf springs??
Lets see those same measurements up at the operator station.. bet we lose a lot of those dramatic numbers.
(its why I have waited to find a dyno before flashing my chip - I want to see objective results. I have givin up, and might install it anyway. Guess dyno testing motor homes is not a thing around here. Will I see improvement? I sure will be looking hard, as it cost $400. I would like to have the 'hard numbers' from a dyno, put them aside, drive it and see what the 'butt dyno' says. Then read the sheet and see how close I was to the measurements. Keeps me 'honest' to myself, and offsets the influence the wallet has. )
