i recently downgraded big time. i went from a d15b7 to a d15b8 and am really noticing a difference. anyone know how different the ratios are in the trans or why my rev limmiter dropped 1000 rpms to 5500?
i almost think it could be controlled by the speed sensor I
had code 9 (#1Cyl) before swap and no effect on redline.
used old distributor, computer and harness.
the extra rpms would help but not much. This car is SLOW.

any help will be greatly appreciated
