Steve,

I'm sorry to see/hear that you are dissapointed with your visit to our facility. I am happy to read on here that other owners are not particularly suprised with the dyno numbers that you are seeing based on your particular combination. As mentioned while you were here, it is IMPOSSIBLE to calculate and exact parasitic drivetrain loss or a specific dyno percentage loss as compared to other brands/facilities. Also, it would be wise to take into account that a companies advertised power increases are never exact and each and every car reacts differently to modifications, weather conditions, altitiude, baro pressure, ect ect ect. Just because someone elses car makes X whp and Xwtq in Washington State obviously doesnt mean that your car, or even that car will make that same power in Florida (or Kentucky for that matter). I'm sure you are aware of that aspect however.

As far as the "100 mph" thing that you mentioned. I had/have no problem taking that dyno to 160mph (which is what it is rated at) and have done so multiple times before. I saw no reason based on your cars output graph (refer to the one you posted originally) to take your car beyond where we did. As you can see the HP levels were leveled off and there were no significant gains to be had over where we were. (Possibly 1-3 whp). I would have had no problem taking it higher for you had you mentioned it while you were here. There is simply no need to beat on it any more then nessasary if you are not going to see any gain from it in my opinion.

Also, with the fuel curve I was seeing on the dyno and my experience with tuning cars, I have to come to the conclusion one of three things. Either A: your tune is off and your car needs to be leaned out in the upper RPMS, B: your tune is off and your car is adding fuel based off of excessive knock voltage to protect itself, or C: your tune is spot on and the IAT's on your car are excessively high do to the added boost through the stock heat exchanger and the computer is adding fuel based off these values to cool the combustion and protect itself from knock. In either event, this is also another reason not to take your car any higher in the RPM's then we did while we had it here. The computers will also learn based on the conditions and driving styles of the owner and it could have been seeing these higher IAT's for some time and just trimmed the fuel curve richer based on this condition.

In either event, I am sorry you were not happy with your experience here or that you did not find our facility to be as nice (or as "state of the art" I believe you put it) as you expected and if there is anyway that I might be able to help correct this I am open to suggestion. Please feel free to email or call me anytime you like.
