Max safe RPMs I'm running Patriot 5.3l stage 2 heads and have been told that my car is shifting too soon. Right now, it shifts at 5900 or so and my rev limiter is set at 6300. Am I leaving a lot on the table or is this OK?

Until I can get a new program, I'll just manually shift and hold the gears a little longer. I was running 12.2s last weekend in drive, so I'll see what difference it makes tonight.

This will not work if your rev limit is set for 6,300. I would recommend setting the rev limit for 6700-6800, and set the shift points to occur at ~6500 as Predator stated. That should be a sweet spot for your cam. Your '02 short block is fine within this RPM range, just make sure you don't lose oil pressure.

Please do not do that, ever. The transmission will not like you.
