I just got EFI Live and i was wondering if anybody knows what some good shift points are for a 01 silverado 5.3 with pacesetter headers, ORY, flowmaster super 40, and K&N intake. Everything else is stock. If you could post some up, it would be greatly appreciated. Also anything else thats is of good knowledge while tuning.
Most of us have HPtuners.. But i will say it makes a big diff if you have a built trans or not. I shift mine at 6450 1-2 and 6400 2-3. Although that will not help you much b/c our trucks are not the same. I know some N/A guys that are shifting damn near 7k. If you rev your engine that high plan on replacing parts unless you have done your homework on springs, seats, pushrods and retainers. I think you will be safe shifting at 6200 and going from there.

You need to put it on a dyno and get some power numbers. You want to keep the engine in it's power curve and if you go over 6K rpm you really need some good springs like the Comp 928s or 921, PRC or Patriot duals.
If you have a stock cam I don't think there's a lot of gains over 6000....but I could be wrong. Mine shifts at 5900 1-2 and 5800 2-3. Your headers help. I have none.
0 shift times , 0 TM (torque management , both in engine section and trans section, max input and output shaft) , add 10% to line pressure 1-2 , 2-3 .Quote:

5800 to 6000 is good on a stock cam .
Wide-band (LC-1 if you have V2 , digital data) and do AutoVE .
Do you have the V2 or V1 ?
I got V1 Pro
Good unit , you can do a Custom OS with the Pro if you want .Quote:

I wish i had went with EFI Live.....I like the layout and tuning terms better...not easier by no means but better explanations of what does what....
Really need both EFILive , HPTuners and SCT as well for the Dodges and Fords .Quote:

Also i did all of my tuning in the performance mode (tow haul) so everything is normal when in normal mode. Does anybody have a base map they wouldnt mind sharing with me so i can start on the motor. This is my first time tuning so all the help i can get is appreciated.
Take a look at PE (Power Enrichment) , on stock trucks it is way to rich , run something like 1.15 EQ (12.8 AFR) .
Read , read , read as much as you can about tuning and everything associated with it , ask questions about "what does this do?" .
There is a lot to learn , but don't give up , it will come in time .
This site is for Nelson Performance and he uses HPTuners , out of respect to him go to EFILive site and post up some questions instead of here .
