Car shifting sooner than it should

[dukedusterwrx]

Ok this only happens like once or twice a day may be even four times a day i will floor it and it will only shift at like 5,000rpms and doesnt feel really as good as it should whats wrong

When you floor it and it shifts early, are you moving, or is this from a dead stop?

i have not really paid attention but if i remember correctly it is both what is my problem i greatly appreciate your reply thanks

Its from a dead stop. Usually the way the car works is from a dead stop or when the car starts in 1st then it will shift before redline ( however. ) if u are rolling and the car has to downshift into 1st it will take it to the limiter.

I think you might have 2 different things causing this:

1) You have 3.73s with 3.42 programming, this could cause it to shift a bit early

2) Our tachs are inaccurate, the car most likely is not shifting as early as you think it is.

Have you tried using your HPPIII to correct the problem? If it really is shifting too early, just increase the shift points. Do this at the track so you can see how your adjustments affect your 1/4 et's.

the car doesnt shift early all the time just a little bit of the time i have set my shift points on my hpp3 up and moved the rev limiter up but itll smack into the rev limiter at like 6k and i have it set a 6.5k so i dont know if anything will help I looked at the butterfly in the throttle body and when it is open it does not open all the way.

I don't know...maybe you aren't depressing the pedal all the way down? LOL

You moved your rev limiter up to 6500 RPM's? :eek: Thank your lucky stars the car still doesn't rev over 6000 RPM's or you'll be asking why there's a huge puddle of oil under the engine and your engine won't turn over any more!

Unless you have a new valve train setup that can support the higher 6k+ RPM stress, you will blow your engine if you rev past 6000 RPM's! :rolleyes:
