okay to answer the question on rev limiter, I have a nun1 code on my car and with the chip, lets just say that I now can run a quarter mile in 3rd gear... It raises up as much as you are looking for and maybe a bit more, I havent taken it over 7500 so Im not sure when it bounces, Im afriad to even take it that high
but in summary, the chip, especially the superchip from superchips.com will do what you want.
