This is why I (as a customer) use the tuner and dyno that I do, even though he is located in Charleston 4 hours away. He has a Mustang AWD dyno, that from what I understand reads quite low compared to most. My car was like Baby J's, low PEAK numbers but awesome power curve and midrange- even for a big laggy turbo it had a large enough powerband to be usable and a lot of fun. He tunes to make the car fast, not for you to go around bench racing with imaginary numbers. He flat out told me that when I met him to get my car tuned the first time. "If you are here to make big numbers and go home to brag, you are at the wrong place. This dyno is the 'heart-breaker' so take whatever number you think you will make and take about 30-50whp off of it. You still might be too high" LOLOL

I return there, because I know what I made on his dyno before with my setup so I have a baseline, I know what HIS car made on the dyno, and I know what 1/4 mile times he ran with the power his car (same as mine, very similar setup) made on his dyno. Therefore, I can set a whp goal, because it directly correlates to the 1/4 mile time goals that I have also set forth for my car. Just for arguments sake (hypothetical #'s), I know that (driven properly) 500awhp on his dyno should get me in bottom 11's-high 10's in the 1/4. Is it guaranteed? Of course not, it all hinges on driving ability, track conditions, and sometimes it even comes down to dumb luck. But I know with that number on THAT specific dyno, the vehicle should be CAPABLE of the given E.T.

If I am wrong in my understanding, I would like someone to explain to me what perception I have incorrect, so that I will hopefully learn a little something from this conversation
