I was looking for a comparison when I had DL do mine and couldn't find any. I asked DL directly and he said he didn't have a dyno comparison. With him owning a dyno and offering this service, I found this very odd, but went ahead and had him do mine for me anyway.
He put a total of four custom curves on there. Two curves for mild cams and two for higher lift cams. Basically a custom curve for each cam build and a more aggressive curve for each cam build. I had Lucas (English Racing) do a couple back to back runs on his dyno comparing the two curves for higher lift cams (I was running a Web 4) and saw no real difference in them on my build.
I'd still be interested to see a dyno comparison though between the #2 most run and DL's custom curves. Perhaps there are some out there and I'm just not aware of them. If anyone knows of any, please post 'em up.
I have the programable version, but also found it hard to get vendors to tell me why i should pay to have it programmed, so I left it alone. I recently had my quad dynoed. It has big three, but no motor work (yet). I picked up 7hp in the top RPMs from switching from #2 to #3. position #1 is supposed to be stock.
I should add that the builder who dynoed the quad had previously been able to get more power with out the Dynotech. We were both suprised with the results. I would suggest doing a few pulls stock, #2 and #3 before really tuning it in.
with dl compared to curve2 i pickup 2tq all over the power band and straighten the power band at the over rev 7500+,under there i didnt see difference in hp.i saw a dyno sheet somewhere here from dl that its 1-2 hp over curve 2.
