don't know if it's the case here....but i don't think i'd trust a graph no matter how fancy from the same firm that charged me for the testing.

I'm sure that I'm missing something obvious here, but where I come from a chart is simply the visual representation of the data produced by the dyno run. What's not to trust?

check with bernie madoff's clients that lost billions of dollars worth of investments. they were sent offical-looking "investment summaries" for decades showing false information as to how much money they were making...all of it false and all designed to give them what they wanted to hear. making up info that shows up on those charts is child's play.

the only way to come close to an accurate number is to compare two or three tests from different vendors and take an average. and guess what? they KNOW that 99.99% of clients will be satisfied being given, once, what they wanted to hear in the first place.

I'm probably super naive, but are shops that do tuning and dyno testing notoriously Bernie-Madoff dishonest? Or are we just prone to conspiracy theories?

No conspiracy theories going on with the dyno graph. It's legit. Don't focus on the peak numbers though for a few reasons. Rather, look at the gains between baseline and post-headers. There are significant increases from mid-top end regarding both power and torque. Maybe even more importantly, there aren't any dips anywhere in the entire rev range after the headers were installed. Unless there's a CEL, I don't really see a reason to tune unless A/F ration should be adjusted.

I bought the headers lightly used from a local seller and installed them myself. Like most shops with in-house dynanometers, this one simply charges anyone and everyone who is willing to pay $150 for 3 dyno pulls with graphs. They do no tuning and don't even work on Porsches... it's a shop for Evos and Minis. The shop couldn't care less what the results are. I dyno'd the car a year ago and went back, they dyno'd it again, then overlaid the charts. The whole ordeal takes less than an hour and they literally just print it after the runs. There is no manipulating the graph... the program simply creates the graph while the car is still running on the machine.

Maybe you're not familiar with dynos?? Not sure what you are skeptical of.

No negatives. The sound is intoxicating.

Such skepticism of dyno graphs can only come from someone that lacks familiarity with them and how they work, and likely has never dyno'd a car. You literally see the graph made while the car is still on the dyno.

There is a CEL because there's no cats on the car. It's been that way since they were installed 12 months ago. The only reason to get a tune is if someone doesn't want the light in their cluster. Doesn't really bother me. I'm tempted to get a tune just to do another dyno run to show how little difference it makes vs headers alone.

bernie could make up a fake investment invoice while you waited. but the point is that people are fed what they want to hear from service companies that are dependent on satisfying their clients. it's simple human nature. ask the salesman at your next fitting if you look good in the $1500 suit you're trying on. or a any car salesman if the car you said you're interested in buying is any good. ask a maitre de of the food is any good. ask a ford executive if they make good cars. ask the president if GM is the leading EV company. get real...

such confidence in software and the dyno graphs they create (to take a cue from a contributor) can only come from someone that's not familiar with it, and how it works, and likely has never worked in the field where one can literally make the graph, made while the car is still on the dyno, look like anything that's necessary to satisfy the client..

simply saying that that dyno's are fallible and subjective and realistically, one needs multiple tests to get anything close to a realistic assessment of whatever's being tested. ..i think you all know that.

Do you know what a Dynomometer is measuring and where teh data comes from?

How do we know the car being dyno'd is actual a car? You need at least three opinions from experts before you can, in fact, claim what you have is actual a car. Wake up sheeple.

Getting back to earth, I can tell from my butt dyno when I've added 10percent more power. Zach L how does it feel subjectively?

What you're implying with that analogy is that the same business who runs the dyno also manufacturers and/or sells the headers. The headers were bought used. The dyno place....you know what never mind

Ordered a new OEM window regulator for my passenger side. And some replacement trim pieces/panels to replace what the paint shop broke.
