also, adding to tomps explanation, your tune as tables dedicated for your shift points. Shift speed, mph points, WOT shift tables, etc... all work together. Can you explain at what rpm this happens more frequently at?

Anyways, combined with a wack, twin timing tables and most likely a peaky ve table, combined with a stock stall converter, might yield into some deadspots in the trans/rpm range.

I would love to get my dynatechs in and see how well they would do with the stock exhaust. Then add a cutout and see what that those...

long tubes, like TAZ mentioned, should wake her up a bit, and with a intake, you should feel, if not hear, some difference in performance.
