You could buy a flasher or programmer. SCT, Xcal, hypertech.. they all do about the same thing. I would NOT remove your rev-limit. If your going to remove the speed-govenor, sure, have good tires, but a lead foot with no protection for the engine is another story.
Maybe have the limiter for rpm's bumped up a notch, but I wouldn't suggest fully removing it.
Panzer.. I say this in all kindness.. You sound young and impressionable. Before worrying about the speed limiter and rev limiters, please take an understanding as to why they are there.
Your truck tops out at 92mph due to the TIRES that came on it from the factory. Rangers are usually stable to about 120mph, then they become rather violent at 130mph-ish. The tires that came on it arent worth a damn after 110mph, you might as well be on a sheet of ice with what marginal grip they have ( regardless of what they are rated at ).
Pushrod engines don't like rpm's the way an OHC engine does. Theres a floating valvetrain that really doesn't enjoy higher rpm's. If you have an SOHC engine, you might bump those rpm's up a little bit, but the power increase you will *believe* to see really *won't* be there.
Having 1000 HP is GREAT! You also need a tranny, axle and tires to handle the power.. then brakes cause you have to stop sometime, even if for gas
. Its a ' system ' of things.
I think you should look into what all is involved in those flashers and programmers, check your tires ratings and make sure everything will ' mesh ' together before spending 350+ dollars on something you will probably see little gain or function out of.
