So who is getting what results and what seems to work the best for shift times and pressure, also any other info on what everyone is running and what seems to work the best would be great. I have the DHP PowrTuner in case anyone needs to know

Can't really say. Most of us are still working on engine tuning and haven't even got into the transmission yet. Until more people start testing and posting results, we don't really have a set of guidelines for a starting point. Best bet is read the tuner guide and start off with their guide lines. Then pick something you want to improve, make one change at a time, and test drive it to see how it's affected. It's a trial and error process and no one can tell you exactly what the best setting will be for your car.

not only is what Aaron said true for most but also the "best" shift Time/Pressure tables is a matter of personal perference as well as being limited to the condition and quality of the parts in the transmission... for instance, having the upgraded accumulator pistons allows us to run higher shift pressures with little to no worry about the pistons breaking or cracking like the OEM ones...

Im sure everyone knows (or can figure out) why I dont post more on this but I hope that helps to some degree

So basically unless one wanted to trash their stock tranny as an excuse to get a new one there is a limit to how high the line pressure can go?

Yes, there is a limit, with the stock parts you can set the pressure too high, it might not break anything, but the transmission will freakout and take longer to shift even though its commanded to shift quicker. Like said up there before you have to find the happy medium of things. I know with my trans it hated the line pressure maxed. It couldn't decide what gear it would like better and bounced back and forth between the two and all we messed with was line pressure.
