Just wanted to get some input on my shift points and where you guys are shifting at. Right now I am shifting at 5900ish that's where my tuner has is set at but still feels like it is still pulling up top. Any input would be great in which direction I should go.

I would say you are cutting yourself short. I'd think 6200 ish would be good with your cam. I usually setup stock engines around 5900 to 6100 depending on exact model.

My cam only makes power to 5500rpms on a dyno jet & 6000rpms on a mustang. I have mine shifting @ 6500. Seems to be doing just fine. If your rev limiter is set higher just try to manual shift it to see how it does.

id say get a dyno and have your tuner adjust the shift points accordingly

Agree with this, but just for some info. Back when i was stock my Tahoe was a good amount quicker shifting at 6200rpm vs 5700. Yourse seems a little low to me, but there are alot of factors to this

I might get on a dyno after I get settled in up in Fort Lewis Wa. Just have to find a good dyno up in that area.

I picked up EFI Auto Cal and going the street tune route now....Ran about 50 minutes of logs tonight and sent them in. Can't wait to see the improvements!

I bet your setup will enjoy some more rpm! What converter are you running?

I'm running a Trailblazer I6 stall. Wide open throttle it will flash to 2600ish. I think a nice 3200 stall and built trans is next on the list along with a nice set of 3.90 gears and a try trac
