Yes Miles does great work, he's heading out to China again next week! Once he gets back I'm getting my Exhaust done! Going to drags this week? What your setup?

+1 on Fine Line. I was there this morning talking to Ryan about installing some gauges. They tuned my stage 2 '05 STI, 285whp and 310wtq and I still average over 20mpg driving not so conservatively! You wont regret it!

What gauges you thinking about? I have wanted to get some myself! I'm just worried about the Police! Around Petaluma they try to get yah for anything! They see gauges it gives them a reason to hassle you! Why I am going to do exhaust cutout, cop told me next time it's a REF ticket. They see that APS can hanging out the back and they pull me over!

Most dynos these days are load bearing except for dyno jets. Mustang, dynapaks, dyno dynamics, Dynocom, and even dynomites are load bearing. They all read differently of course, but it's not about the absolute numbers but rather about the consistency and repeatability of the equipment that's important. Remember the dyno is only a tool. Just like with any other tool, it's all about how you use it.

If they are load bearing dyno's why do they read so different? Im sure it has to do with how its calibrated! The Mustang dyno always has the most realistic numbers? Ed your dyno seems closes to a mustang dyno, I have noticed your torque always looks on the higher side.
As far as what numbers are most "realistic", that's tough to say and largely a matter of opinion. This brings the point again that none of the numbers should be looked at as absolutes but rather compared to baseline numbers. The % change is the important part.
My dyno specifically, reads more like a dynojet in its natural state. Since I was always used to lower numbers from my road dyno software which reads similar to most Mustangs, I run a .85 correction factor on my Dynocom to make it read like the lower reading Mustang dynos.
As far as the torque being higher, that has to do with several factors. One major factor is the style of tuning. I like to try to maximize the area under the curve which often means having a higher torque peak. My tunes have always had better than average torque because of this. Another factor is the resolution of the dyno. A dyno that has greater resolution will be able to measure quick torque peak and show it in on the graph. With lower resolution, that torque peak will be averaged over and the resulting peak number will be lower. The final factor that is similar to resolution is the smoothing/filtering value that the dyno operator uses. When more smoothing is applied to the graph, any quick torque peak will also get smoothed over and the peak value will be lower. I generally run minimal smoothing on my dyno which in turn shows more resolution to the graph and will show a quick torque peak that would otherwise get averaged over.
I hope this all makes sense. Its important to remember that none of this is necessarily right/wrong, they are just different methods and tools we use as tuners to try to provide the best results for our customers.
Thanks

^^^^^^^ good info! I understand that a dyno is just numbers, most don't think that way! I think if you had 3 different good tuners tune the same car on the same dyno they all would be very close in numbers! I don't think that one tuner can get a extra 50whp out of the car running same boost! Most check out dyno numbers and think wow that 20g has 50whp more then mine with same PSI and same turbo and setup but different tuner and dyno! I know ever tuner has different ways of going about things, all similar in the long run if dealing with a good protuner! Ed knows his ****.......

People should forget about numbers, they really mean nothing. Taking a baseline and graphing gains and losses with a given tune is the only benefit of a dyno as Ed said, its just a tool to consistently measure. If you want to show off some crazy dynograph to someone and then make your own on photoshop, lol. Take your car to the track those numbers will tell you how fast your car is, realistically.

or try mayhem tuning from reno. he'll come to you and road tune. he just tuned my 07 e85 sti
