whats the cheapest way for me to be able to adjust the rev limiter on my formula?
When madz28 did the tune, he turned it up to 6000, which is cool, but I'm considering getting into autoxing, and if I do, I will probably end up letting my brother-in-law drive it some too.
I have a feeling he will run it out to the rev limiter a lot, so I would like to be able to turn it up and down.

any thoughts on autoxing the daily driver car? I'm a little leery, but at the same time, I can't imagine that we could really hurt it either.

 

Get editing software (LT1_Edit of TunerCat) or find a cheap used Hypertech programmer (making sure the previous owner returned his car to stock before trying to sell the programmer).

 

An aftermarket ignition box such as the Accel 300 + is relatively cheap and will allow you too control your rev limit.
Plug and Play as well.
I had my stock rev limit adjusted to 6500 and control my rev limit with the box.
