11.4 hP - it is amazing how much those 11HP translate into on the road stomp 
this car just plane gets it now Bonny(the driver)
informed me on Friday that the redline of 7800K is crazy.. (Jan raised the redline to 78k but we only dyno'd her to 7K)(her words)
I was racing a 350z up the on ramp and as I was pulling away on him the rev limiter kickied in and scared the **** out of me when it cut out at 7.8K
(her words)I told her if she keeps that up I will be putting a 2.0 stroker in Lilly - i am not sure if that is a threat or a promise
Jan - True Dat - your see'in the dyno sheet as is, no smoke - no mirrors at MORE than 1 mile up, 6600 ft at Macs at 84 Degrees.
Silver - Thanks
KC - I am not sure what the conversion would be but I would love to see this car at sea level
all I know is up here going to work I can romp WOT and she breaks the tires loose then the limited slip catches and she launches, then she breaks loose again, then the LSD catches and she launches again, then repeat until I shift to 2nd . I LOVE THIS THING - oh Yea I live at 7,250 FT - Did I mention I love this car

After reading this thread, it made me pull out the good old thermodynamics textbook and review some tables.
At 6600ft and 84 degrees F, the barometric pressure is approximately 11.3 psi compared to 14.5 psi at sea level. 11.3/14.5= 77.9% which means it is approximately 22.1% less powerful than what it would be measured at sea level. With that reasoning, the car would have 250.2 hp at sea level? How is this possible without going to a BV cylinder head?
What am I missing?

One thing I have to say about the RMW tune, I have to look at the tach to know when to shift. I just don't feel any loss of power as it revs up, it just keeps pulling (I have hit the rev limiter more than I want to admit). Maybe I should get one of those stupid shift lights.
True Dat
I bounced the limiter on a regular basis when we first got her tuned and the wife out right destroyed the redline, now I can hear the RPMs and know when to shift. Usually I hear her at about 7K and shift - it has just become instinctive based on feel and sound I do still bounce the limiter from time to time though 
when I am pushing her up the canyon

You are absolutely correct, it feels like it would keep pulling forever, LOL. When I first got the tune, I almost always hit rev limiter in first. Now I short shift a little in first (6500) so as to not do it.
