Shift points higher after stall installed

Shift points higher after stall installed I recently put a 3400 stall in my car. It used to shift around 5700 rpm. It now shifts around 5900 rpm.
Will this damage my valvetrain?
Am I exceeding the power curve of the stock cam?
I do have an STS turbo on the car (kicks a##).
Thanks in advance.

Well turbos like exhaust, and higher RPM generally means more exhaust (but not always). Your valve terrain should be OK, I would think, to at least 6250rpm. As for exceeding the power curve, probably a little, but I wouldn't worry much about it unless you're always racing.

Thanks. I don't always race, but the car is a weekend toy only. I have LT1Edit, so I can easily change the shift points. I want to maximize the performance, so I can play with ricers and that off brand American semi-performance car (the name escapes me 
).

Interesting observation. In the A4 dialog box, both RPM settings and MPH settings are present. It is not readily apparent which one is being used, as there is no control to switch from one to the other. Geez, I love LT1Edit. Not.
I did notice that the section labeled Hot Shift RPM the numbers are in the 5300-5400 range, which is clearly not the case.
Does anyone know how to make LT1Edit use the RPM table instead of the MPH table?

And of course the user's manual makes no mention of how to switch between the two.
But many thanks for the info; I much prefer to use the RPM table just like I did with my HPP in the bad old days.

As a software engineeer, you should know a radio button would have no function if the file you are trying to edit had no binary switch to select that. You would need to take that up with GM.

At that time you make the decision which setting takes precedence, according to the radio button, and write fake data to the file for the section you choose to ignore. Pretty simple implementation, really. I am a GUI programmer and that is how it is done. To the user it is transparent.
Guess you would be screwed if you had to do it like many of us did it for 15 or more years, with a hex editor.

Actually, I use a hex editor in my job. I grab data from a satellite, load it into a hex editor, and decode it byte by byte, sometimes bit by bit. Doesn't mean that I like it, especially when I get off by one or two bytes. I was a DOS head for years, and it took me a long time to appreciate a GUI. But that is why GUIs are so popular, they take a simple to visualize picture and do the meat and potatoes work in the background.
Kind of what those macaholics have been crowing about for years.
