I had my car programed to shift at 6,000 rpms but it seens to shift at 6500, and since I put the 3500 stall in it shifts around 6,700 1-2 shift and hits the rev limiter at 7,000 before the 2-3 shift. I know the rev limiter is not set that high. I think the rpms are off by 300-500 rpms. Has anyone else experienced this problem?

The factory tachs are well known for not being the most accurate from car to car. You should also datalog it to see what RPM the computer shows. There is generally a little flare during shifts that you have to account for, anyway.

The factory tach is 200 rpm's ahead of what the motor is actually turning. It for ******** that go test drive something and beat the **** out of it. Pushing redline way too much.

When i installed my digital shift light you could really tell at idle.

I remember when I got my re-tune back from Bryan at pcm$less it would idle at 1100rpms when I asked for 900? I thought he just did what he wanted or ignored my request but after i installed it was another story. Sure enough, the shift light said 900.
