Shift points

I just got the Hypertech power programmer and it has a area for changing shift points. What should I change it to optimize shift points? 1 mph adjustments it has on there. Thanks

Not getting my manual out to see the setting options, seems like it had 6 incrimental settings, I went all the way to the quicker, harder shift point and love it.

It shifts quicker and very firm when accelerating moderately to all out.
You can always change it by reprogramming it anywhere in between.

Try it, you'll like it, guaranteed.

Well tonight I adjusted the shift points I gotta say Im impressed and worried alittle too. I changed mine to +6 from 1st-2nd, +3 from 2nd-3rd, +2 from 3rd-4th. I got rid of that dead spot from 30mph to 40mph that I addressed in earlier trends. I also broke the azz end loose at 46mph. I was impressed. But I also noticed that Im tachin out past the 6000 rpm mark. I did set the rev limiter for 6400 like the book says but is this to harsh?

If this is on a stock LT1 valvetrain, YES.

no reason to run a stock LT1 that high.

I wouldnt set it any higher than 5800 just to be safe, maybe even 5500. Of course its always a good excuse to upgrade the heads and valvetrain

I think the stock is 5500 anyway. Ill change it to 5800 to be alittle safer. But why does the "Power Tuning" ,which sets low fans, 160 stat, firm shifts, top speed eliminate, and rev to 6400, set it to that setting automatically? Im going to email hypertech and find out more.
