That depends on owner preference. I start in part throttle tuning with an increase of 3 MPH under 50%, and add up 1 or 2 MPH from there. Dont forget adding the same amount up to your downshifts.

that's the hard part about the tranny tunes. I may like one shift range, another tuner likes a differant range, and the owner doesnt like either and may want it higher or lower/ softer or harder shifts.
The transmission tune is driver/owner objective.
I did an F body last week, and he liked everything about the tune, but after a couple days of driving, he wanted the shift points lowered
2 MPH in part throttle, so he came back that day and I lowered them. It took 10 minutes to change and scan, but its owner preference.
Call your tuner and communicate your feelings, and it doesnt take long to change.

Depends on many factors---especially rear gear ratio---a ratio like a 2.73 will tend to short-shift and lug while driving around town---i like to tune A4's by letting the engine RPM's hover around 2000- 2200 RPM's when shifting under normal driving accelation --It prevents the engine from lugging which makes it a dog and is horrible for fuel milage
Sound like you are using a handheld tuner---A handheld does not address shifting tables prperly--at PT they don't adjsut the downshift points-- at WOT that's a whole new thing--The ECM must hit 2 parametrs in order to command a shift--1st it must hit the commanded MPH and then hit the commanded shift at RPM point-- a handheld does not address these properly either---only a full tuner like EFILIVE or HP does---there are so many things a real tune can do do make our car quicker without adding a single HP !!! i've seen gains of up to 1/2 second in the 1/4 mile--- The WOT downshift tables are huge as well

For the most part I'm loving the new found power of the V-2 and the tune. Just noticed that it seemed to short shift 1>2 on normal driving so when I got HP tuners I was looking at the tune and noticed that it was set to shift at 11 MPH at 6% TP graduating to 28 at 50% TP. Easy enough to change the numbers and see how I like it. Just wondering what others had found to their liking.

There isn't a RPM table for P/T---The only way to get the shifting to hover around 2000 2200 RPM's is to make a change and drive it to see where the RPM's are at-----trial and error--
EFILIVE does have a calculated RPM for PT shifts that you can use as a reference or starting point--but the real only way to get it accurate is to drive it--

Thanks all for the responses. As I learn more about HP Tuners I'm sure things will become clearer. I want to especially thank Phil (Phils C5 Vette) for answering my questions and even took a look at my tune and offered up some changes. His time spent and information he gave me was invaluable. When I offered him some payment for his time he refused. Thanks Phil.
